Emergency Scene Lighting: How to Choose and Mount Scene Lights on Your Rig
At 2 a.m. on a dark road, your crew can only work as safely as they can see. Here's how to light a brush truck, rescue, ambulance or engine in layers, what the spec sheets really mean, and how much your electrical system can carry.
Pole lightBody scene lightsBrow lightPerimeter lights
The short answer
Light the scene in layers, with several smaller fixtures instead of one giant one. Perimeter lights cover the ground right around the rig, body-mounted lights cover the sides and rear, and a brow or pole light reaches across the scene. A remote spot or portable light covers what the truck can't. Mount side lights at the body edge so they don't cast a shadow, compare effective lumens (the light that actually leaves the fixture) instead of raw, add up the amps before you buy, and aim everything at the work, not at approaching drivers.
Who this guide is for
If you're like a lot of volunteer and small departments, you aren't ordering scene lighting as a factory package on a new engine. You're adding it a few lights at a time to the trucks you already run, usually on a 12-volt system and a tight budget.
That's who this is written for: volunteer and small-department firefighters and EMS crews, and the member who ends up upfitting the trucks. Spec'ing a new apparatus? Your builder handles most of this, but the principles are the same.
By the end you'll know- Which layers of light your rig needs
- How to read lumen, amp and beam ratings
- Whether your electrical system can carry it
- Where each light goes, and how to use it at night
A brush truck runs on a pickup's 12-volt system, so keep the power draw modest. Low-draw ground lights, a pair of side scene lights and a magnetic remote spot cover most calls. Add a battery-powered portable for off-road work.
Crews work out of compartments on both sides. Light the ground and both sides, then add a pole for the wider scene and a remote spot for reach.
Scene lights over the side and rear doors where crews load, plus low strip lighting for footing.
A remote spot does most of the work, and ground lights mark the command post.
Engines carry the biggest lights and the biggest electrical loads. FAMA says the apparatus builder's engineers should review any lighting package to make sure the electrical system can carry it.

Learn the layers: what each light covers
The takeaway: no single light does it all. Ground, sides, front, distance and the places the truck can't reach each need their own layer.
Scene lighting is the white light your crew works by. It's separate from your warning lights, which face traffic. No single light can cover a whole scene, so you build it in layers, and each layer covers a different area around the truck.
How to use the map: tap a layer to switch it on and see the area it lights. The lights that do that job appear underneath. Tap it again to switch it off.
As you add layers, watch where the circles of light overlap and where they don't. A bright hot spot next to a dark patch is hard on the eyes and can hide a hose line or a trip hazard. That's what the Fire Apparatus Manufacturers' Association (FAMA) means when it says the best packages keep the "highs and lows" to a minimum.
Perimeter and ground lights
Small lights mounted low on the body, aimed straight down at the ground around the truck. They light the steps and the ground where crews climb on and off and pull equipment, so nobody steps down into the dark. This is the area NFPA's minimum light levels cover (see the standards table below).
Shop perimeter and surface-mount scene lights →Body-mounted scene lights
Lights mounted on the sides and rear of the truck body. They light the area right next to the truck, where your crew pulls tools from compartments, runs the pump panel or loads a patient. They're wired in, so one switch in the cab turns them on, and nobody has to carry out or set up a light.
For full-size apparatus, FireTech's Guardian lights are in our scene lights for fire trucks collection.
Shop scene lights for fire trucks →Brow lights
A long, low light mounted across the front of the cab roof, like a brow over the windshield. It floods the area in front of the truck, which is usually where the incident is when you pull up, and it comes on with a switch, with no setup or aiming. One catch: the roof is also where the truck's required marker lamps sit, and a brow light can't block them (Step 4 explains).
Shop FireTech brow and area lights →Pole and mast lights
A light on a telescoping pole that raises it well above the truck. From up high, the light spreads wider, casts shorter shadows and shines down instead of into your crew's eyes, and FAMA notes the height gives you more freedom to aim. It's the layer for lighting a large area, like a whole crash scene or the yard around a house fire.
Shop scene lights →Remote spotlights
A spotlight on a motorized roof mount that you aim from inside the cab with a remote control. Its narrow beam reaches far, so you can read a house number, search a hillside or find a vehicle that went off the road. Drag the slider below to aim it on the map.
Portable and tripod lights
Lights you carry off the truck and set up on a tripod, powered by a battery or a cord. They reach places the truck-mounted lights can't, like the back of a building, down an embankment or inside during overhaul. If you run one on a long cord, plan on AC power from a generator or inverter: FAMA notes 12-volt DC power loses voltage over a long cord, so the light at the end can come out dim.
Shop portable scene lights →A light at the outer edge of the body shines straight down the side of the truck. Set it back from the edge, behind a step or ledge, and the body blocks part of the beam, leaving a strip of shadow right where your crew walks. That's why each side light needs a spot at the outer edge.

Read the spec sheet like a pro
The takeaway: compare effective lumens, not raw. Watch the amps, because they add up. Match the beam to the job.
A scene light listing can show eight or more numbers, and brands don't all measure them the same way. Only a few matter when you're comparing lights. The example sheet below uses real specs from lights UBL sells. Tap any line to see what it means and whether it matters for your truck.
Example spec sheet · tap any line
Lumens, watts, amps and voltage from the FireTech Guardian Surface Scene Light listing. Beam from the Whelen Arges 2, IP rating from the Feniex Perimeter Down Light, and candela from the GoLight GT.
Raw lumens
10,000
What it meansEverything the LEDs put out, before any of it is lost inside the fixture.
Why it matters to youIt's the biggest number on the sheet, so it's the one brands advertise. But some of that light never leaves the fixture, so raw lumens overstate what you'll see on scene. Look for effective lumens next to it.
Effective lumens
6,500
What it meansThe light that actually makes it out of the fixture, after the lens, reflector and heat take their share. This is the light that reaches your scene.
Why it matters to youThis is the number to compare between lights. Even so, FAMA warns that each manufacturer tests lumens its own way, so two lights with the same rating can look different on scene. If you can, see the lights at night before you buy.
Wattage
75 W
What it meansHow much electrical power the light uses.
Why it matters to youUseful if you're replacing old halogen lights. FAMA's rough rule: a 75-watt LED scene light gives about the same usable light as a 500-watt quartz halogen, and a 150-watt LED about the same as a 1,000-watt halogen.
Current draw
5.83 A at 12 V
What it meansHow much current the light pulls from your truck's electrical system, measured in amps. Roughly, it's watts divided by volts.
Why it matters to youThis is the number that adds up. Every light you run at the same time pulls from the same alternator and batteries, so total the amps across all of them. The planner in Step 3 does the math for you.
Input voltage
9–32 VDC
What it meansThe range of voltages the light can run on.
Why it matters to youA light rated 9–32 V works on both 12-volt and 24-volt trucks. AC versions, like the FireTech pole light's 90–277 V option, run from a generator or inverter instead of the truck's batteries, so order the version that matches your power source.
Beam
5° spot to 60° flood
What it meansHow wide the light spreads, measured as an angle. A flood spreads wide, a spot stays narrow and reaches far, and a combo does some of both.
Why it matters to youUse a flood to light the work area evenly and a spot to reach something far away, like a hillside or a house number. The beam slider below shows the trade-off.
Ingress rating
IP67 / IP69K
What it meansHow well the light keeps out dust and water. IP67 means dust-tight and able to survive being briefly submerged. IP69K adds protection from high-pressure, high-temperature washdown.
Why it matters to youScene lights live outside in rain and road spray, then get hit with a pressure washer back at the station. See IP ratings explained.
Peak candela
544,000 cd
What it meansHow intense the light is at the very center of the beam.
Why it matters to youIt tells you how far a spotlight can reach, not how much area it lights. You'll see it on remote spotlights like the GoLight GT, and it's the number to compare between them.
See it: same lumens, different beam
FAMA's guide compares light to a hose line. Lumens are the gallons per minute: the total coming out. The optics are the nozzle pattern. Lux is the water that actually lands on the target. A straight stream and a wide fog can flow the same GPM and hit very differently, and light works the same way.
Drag the beam angle below. The lumens never change, but a narrow beam puts far more light on a target 30 feet away, and a wide beam covers more ground with less light on each spot.
Beam angles from the Whelen Arges, Arges 2 and GoLight GT listings.
Raw vs. effective lumens on real UBL lights
Here's the gap between the two numbers on lights UBL sells. The light bar is raw lumens, and the dark bar is effective lumens, the part that makes it out of the fixture. On these lights, 63 to 70 percent makes it out, which is normal. What you want to avoid is comparing one light's raw number with another light's effective number.

Plan the power: what your truck can carry
The takeaway: add up the amps for everything you'll run at once, then have your builder or upfitter confirm the electrical system can carry it.
LEDs use far less power than the halogen lights they replace, but they still use power. As FAMA puts it, watts are watts: a 150-watt LED pulls about 12.5 amps from a 12-volt system, the same as any other 150-watt load. Every light you add pulls from the same alternator and batteries. On scene the truck is usually idling, when the alternator puts out the least, so anything the lights pull beyond that comes out of your batteries.
Use the planner to add up the total. Pick a rig to load a starting setup, or set your own quantities, then share the total with whoever wires your truck.

Mount it right: six rules from the builders
The takeaway: mount at the edge, keep marker lamps clear, get light up high, and spread it across several fixtures.
Where a light goes matters as much as which light you buy. These six come from FAMA's scene lighting buyer's guide, written by the companies that build fire apparatus. Retrofitting an older rig? Our LED fire apparatus retrofit guide covers the rest of the truck.
Mount side lights at the body edge
A light set back from the edge of the body, especially behind a step or ledge, throws a shadow along the side of the truck, right where crews walk. Mount side lights as close to the outer edge as you can. FAMA suggests lights that stand out from the body on a pedestal or pivoting (trunnion) mount, or bar-style lights along the edge.
Keep the marker lamps visible
Federal lighting rules (FMVSS 108) require small clearance and identification lamps on the roof of vehicles 80 inches wide or more, so other drivers can judge the truck's size at night. A brow light or anything else near the roofline can't block them, so plan its position around them.
Get light up and away
Raising a light on a telescoping pole or tower puts it above the crew, so it shines down on the work instead of into their eyes. FAMA notes it also cuts glare and makes aiming easier.
More small lights beat one huge one
One very bright light makes a hot spot with dark edges, and eyes adjusted to the bright spot struggle to see into the dark ones. FAMA says several smaller lights spread around the truck usually give more even light than one ultra-high-output fixture, and the cost difference is often small.
Plan AC and DC on purpose
Truck-mounted LEDs usually run on the truck's 12-volt DC power. Corded portables and tripods are different: DC loses voltage over a long cord, so FAMA suggests running them on AC from a generator or inverter unless they're battery powered.
Budget for maintenance
Poles, towers, clamps and swivel joints have moving parts. Clean and lubricate them on each manufacturer's schedule so they raise, lock and aim when you need them.
Light the scene, not the drivers
The takeaway: scene lights are for your crew. Aim them down at the work, check the glare from the driver's seat, and turn off what you don't need.
Scene lighting and warning lighting do opposite jobs. Mix them up and you can blind the drivers you're trying to warn.
| Scene lights | Warning lights | |
|---|---|---|
| The job | Light the work area so crews can see | Warn approaching drivers that you're there |
| Color | White | Red, blue, amber, white or green, depending on your role and state |
| Aim | Down, onto the work area | Out, toward approaching traffic |
| Once the scene is protected | Keep what crews need, turn off the rest | Reduce it, especially forward-facing lights on divided roads |
The four checks below come from the MUTCD (Manual on Uniform Traffic Control Devices), the federal standard for traffic control on U.S. roads. Most are written for highway crews working at night (Section 6M.08), but they apply just as well to a crash or vehicle fire on the road. The last one comes from its chapter on traffic incidents (Section 6O.05).
Check the glare from the driver's side
The MUTCD says to check for glare after setup by driving through and looking at the lit area from every direction traffic comes from. At an incident, ask the next arriving unit whether your lights blinded them on the way in.
No dark pockets
Drivers need to recognize a person in the road as a person. The MUTCD says to keep shadows from hiding workers, so look for dark gaps between your lights, especially where crews move between the truck and the work.
Enough light for the task
For night road work, the MUTCD says an average of 5 foot-candles can be enough for general work, and precision tasks can need 20. A foot-candle measures how much light lands on a surface. Treat these as a rough guide at an incident, not a rule.
Turn off what you don't need
Section 6O.05 says floodlights and headlights that aren't needed for lighting the work should be turned off at night. Their glare makes it harder for approaching drivers to see, including seeing your crew.
Scene lighting is half of a safe roadside scene. For the warning half, see lighting a recovery scene and our warning lights for firefighters.
What NFPA actually requires
NFPA 1901 does not require scene lights on fire apparatus. It does set minimum light levels on and near the apparatus, measured in foot-candles (fc) and lux. FAMA's buyer's guide summarizes them from the 2016 edition:
| Area | Minimum |
|---|---|
| Rear of the apparatus (a 10 × 10 ft area) | 3 fc (30 lux) average |
| Ground within 30 in of the apparatus where crews get on and off | 2 fc (20 lux) |
| Hose bed, with hose and dividers removed | 3 fc (30 lux) average |
| Work surfaces, stepping areas and walkways | 2 fc (20 lux) |
| Aerial device tip | 75,000 beam candlepower or 4,000 lumens |
Most of these minimums cover the ground, steps and work surfaces right around the truck. That's the perimeter layer's job, which is why every starting setup in the planner includes perimeter lights.
For apparatus contracted after January 1, 2024, NFPA 1900 replaces NFPA 1901, along with the wildland (1906), ambulance (1917) and aircraft rescue (414) standards. If you're writing a spec for a new apparatus, work from the current standard with your apparatus builder.

Scene lighting FAQ
Does NFPA 1901 require scene lights on fire apparatus?
No. FAMA's scene lighting buyer's guide notes that NFPA 1901 doesn't require scene lighting. It does set minimum work-lighting levels on and near the apparatus, such as 2 foot-candles (20 lux) on the ground within 30 inches of where crews get on and off. For apparatus contracted after January 1, 2024, NFPA 1900 replaces NFPA 1901, so work from the current standard when you write a spec.
How bright should scene lighting be?
There's no single number for every scene. NFPA 1901 (2016) set minimums around the apparatus, such as 2 foot-candles on the ground within 30 inches of where crews get on and off and an average of 3 foot-candles across a 10-by-10-foot area at the rear. For night road work, the MUTCD says an average of 5 foot-candles can be adequate for general activities, and precision tasks can need 20.
How many lumens does a fire truck scene light need?
FAMA says typical fire-truck scene lights are about the size of a 500-watt quartz fixture, or an LED fixture of 10,000 lumens or more. It also warns that lumens alone don't compare well between brands, because each manufacturer measures differently. Compare effective lumens where they're listed, and see the lights at night before you commit.
What's the difference between raw and effective lumens?
Raw lumens is what the LEDs produce. Effective lumens is what actually leaves the fixture after optics and heat losses. FireTech's Guardian lists 10,000 raw and 6,500 effective lumens, so compare effective figures side by side.
Should scene lights be AC or DC?
Lights mounted on the truck commonly run on the 12-volt DC system, and many LED fixtures come in both versions. The FireTech Guardian pole light, for example, comes in AC (90–277 V) or DC (9–32 V). FAMA's guide notes DC loses more voltage over long cord runs, so portable and tripod lights should usually be AC unless they're battery powered.
Where should I mount side scene lights?
As close to the edge of the body as you can. FAMA's guide shows that a light set back from the edge, especially on a stepped body, throws a shadow along the side of the truck. Pedestal, trunnion or bar-style fixtures mounted at the edge avoid it.
Can I put scene lights on a pickup or SUV?
Yes. 12-volt fixtures like the Whelen 600 EZ (10–30 VDC) or the Feniex Down Lux (1 A) work on light-duty vehicles. Add up the draw first, since a few scene lights can pull more current than people expect. Our guide to equipping POVs covers volunteer setups.
Should I leave scene lights on once the scene is set?
Only the ones your crew needs. MUTCD Section 6O.05 says floodlights and headlights that aren't needed for illumination should be turned off at night, because glare impairs approaching drivers' night vision.
