Emergency Lights for Trucks: How to Build a Complete Setup
The brightest light isn't the goal. Being seen from every direction is. Here's how to cover all four zones of your truck, what a Starter, Standard and Full build includes, and what it costs with real UBL parts.
The short answer
Light your truck by zone: grille or dash lights for the front, running-board or hide-away lights for the sides, a tailgate bar for the rear, and a roof or mini light bar up top. With UBL parts, a Starter setup runs about $224.96, a Standard build with a roof bar and rear coverage about $794.94, and a Full build with side lighting and a siren about $1,509.90.
Think in four zones, not one bright light
A single light bar on the roof can shine right over a low sedan, and a grille light does nothing for the driver coming up behind you. Plan coverage by zone instead: each zone has a job and a tool built for it. Tap a zone to see what covers it.
Four zones, one setup
Click a zone to see what covers it. Front and rear protect you on the road; sides cover intersections; up top buys you distance.
Front: Traffic you're heading toward, and drivers looking in their mirror.
Sides: Intersections and cross traffic, where drivers approach from the side.
Rear: Drivers coming up behind you while you're stopped.
Up top: Distance. A roof-level light is the first thing other drivers see.

Will Z-Flash fit my truck?
Z-Flash modules flash the lights your truck already has: headlights, turn signals, reverse lights and more, depending on the model. They plug in instead of cutting into the wiring, which makes them a fast way to add warning to a Starter build. Each module lists the exact trucks and years it supports. Pick yours:

From each module's vehicle list on ultrabrightlightz.com, October 2026. Some years carry notes on the listing, so choose your exact truck on the product page.
Notes for the F-150, Super Duty, Silverado, Ram and Tahoe
The zone plan is the same on every truck. What changes is tailgate bar size, which Z-Flash module fits, and how much roof you have to work with.
Ford F-150
- Rear: the 60" UBL Tailgate Bar is the size UBL lists for F-Series trucks.
- Factory-light flashing: Z-Flash lists an OBD module for 2011–2016, the BCM Plugin for 2016–2023, and the BCM 2300 for 2024–2026.

- Z-Flash: OBD module for 2007–2016, BCM Plugin for 2016–2022 (1500), LCM 2500 for 2022–2026 (1500).

Emergency lights for trucks: FAQ
What emergency lights do I need on my truck?
Plan by zone, not by brightness. Cover the front with grille or dash lights, the sides with running-board or hide-away lights, the rear with a tailgate bar, and up top with a roof or mini light bar. That combination keeps you visible to drivers approaching from any direction.
How much does an emergency light setup for a truck cost?
Using UBL parts at October 2026 prices, our example Starter build (dash light, two grille lights and a switch box) comes to about $224.96. A Standard build that adds a mini roof bar and a 60-inch tailgate bar is about $794.94. A Full build with running-board lights and a siren kit is about $1,509.90. Wiring, fuses, mounts and installation are extra and vary by truck.
What's in an emergency light kit for trucks?
A complete kit usually pairs forward lights (grille or dash), a roof or mini light bar, rear coverage such as a tailgate bar, and a switch box or controller to run it all. Fuller kits add side lighting and, for authorized vehicles, a siren and speaker.
Can I add emergency lights to my truck without drilling?
Yes, for parts of a setup. The UBL U-Lite Visor Bar Mini ships with a cig plug and universal brackets. The Whelen Mini Century comes in a magnetic-mount version. The Acari low-profile platform lets you mount rooftop gear without drilling. A Z-Flash plug-in can flash your factory lights on supported trucks without cutting into the wiring.
What size tailgate light bar fits my truck?
UBL's listing recommends the 49-inch tailgate bar for mid-size trucks like the Colorado, Tacoma and Ranger, and the 60-inch bar for full-size trucks like the Silverado, Sierra, Ram and F-Series.
What emergency light colors can I put on my truck?
It depends on your state and your role. Volunteer firefighters, EMS, tow operators, construction crews and private vehicles are each treated differently, and the rules vary by state. Check your state's rules before you order.
Does Z-Flash work on my F-150, Silverado or Ram?
On many model years, yes. For example, the Z-Flash BCM Plugin for Ford lists the 2016–2023 F-150, the Z-Flash LCM 2500 lists the 2022–2026 Silverado 1500, and the Dodge/Jeep/Ram OBD module lists the Ram 1500 from 2007 to 2024. Use the finder above, then pick your exact truck on the product page.
Do I need a siren on my truck?
Only if your role and state allow it. Sirens are generally restricted to authorized emergency vehicles. Many tow, construction, utility and volunteer setups are lights-only.
