Planning the Layout

Before beginning the installation process, it is crucial to plan the layout of your emergency vehicle lights. This involves determining the purpose and placement of each light, choosing the appropriate light types and colors, and creating a wiring diagram.

Determining The Purpose And Placement Of Lights

The first step in planning your layout is to assess the visibility requirements based on your vehicle's function. For example:

  • Police vehicles require lights for pursuit and traffic control, with a focus on 360-degree visibility and attention-grabbing patterns.
  • Fire trucks need lights for scene illumination and warning, with an emphasis on perimeter and area lighting.
  • Ambulances rely on lights for patient care and emergency response, prioritizing clear and directional lighting for safe patient loading and transport.

In addition to visibility requirements, it is essential to consider legal regulations and standards when placing your lights. Familiarize yourself with federal and state requirements for emergency vehicle lighting, as well as SAE (Society of Automotive Engineers) and NFPA (National Fire Protection Association) standards for light color, intensity, and placement.

Choosing The Appropriate Light Types And Colors

With your visibility requirements and legal considerations in mind, select the appropriate light types and colors for your emergency vehicle. Some common options include:

  • Beacon lights. Rotating or strobe lights that provide 360-degree visibility, suitable for roof-top mounting on various emergency vehicles.
  • Light bars. Linear arrays of lights that create a wide, attention-grabbing display, available in various lengths and configurations for different vehicles.
  • Grille and surface mount lights. Compact lights for supplementary or specific area illumination, easily installed on vehicle grilles, bumpers, or body panels.

Creating A Wiring Diagram

To ensure a smooth and organized installation, create a wiring diagram that includes:

  • The power source. Identify whether you will connect the lights directly to the vehicle's battery or use a separate, dedicated battery for the lighting system.
  • Switch location. Determine an easily accessible spot for the operator to control the lights, considering the use of multiple switches for different light functions.
  • Cable routing. Plan the wire runs to ensure they are neat, secure, and protected, avoiding interference with other vehicle systems and moving parts.

Preparing the Vehicle

With your layout planned and wiring diagram in hand, it's time to prepare your vehicle for the installation process. This involves cleaning and inspecting the mounting surfaces, measuring and marking the light positions, drilling holes for mounting and wiring (if necessary), and applying rust prevention and sealant.

Cleaning And Inspecting The Mounting Surfaces

Ensure that the areas where you will mount your lights are clean and free from debris. Inspect the surfaces for any damage, rust, or obstructions that could compromise the stability and security of your lights.

Measuring And Marking The Light Positions

Using your wiring diagram and the manufacturer's templates, carefully measure and mark the positions for each light. Take care to ensure symmetry and proper alignment for a professional appearance and optimal light coverage.

Drilling Holes For Mounting And Wiring (If Necessary)

If your installation requires drilling holes for mounting or wiring, use the appropriate drill bit size for the hardware and take precautions to avoid damaging the vehicle's structure or systems. Always wear eye protection and gloves when drilling or handling tools.

Applying Rust Prevention And Sealant

To protect your vehicle and ensure a long-lasting installation, apply rust prevention and sealant to any drilled holes and exposed metal surfaces. This will help create a watertight and corrosion-resistant installation.

Wiring the Lights

With your vehicle prepared, it's time to wire your emergency lights. This process involves routing the cables, connecting the lights to the power source, and installing the switch and controller.

Routing The Cables

  • Use grommets and wire loom for protection:
    • Grommets help guide wires through holes and panels while preventing chafing and damage.
    • Wire loom is used to bundle and shield cables, keeping them organized and protected.
  • Secure cables with zip ties:
    • Use zip ties to keep wires neat and organized, preventing tangles and clutter.
    • Properly secured wires are less likely to suffer from chafing or damage due to vibration or movement.

Connecting The Lights To The Power Source

  • Fuse the circuits:
    • Install inline fuses to protect your lights and wiring from excessive current.
    • Select the appropriate fuse rating based on the current draw of each light.
  • Use appropriate gauge wires:
    • Ensure that the wires you use have sufficient current-carrying capacity to power your lights safely and efficiently.
    • Using the proper gauge wire also minimizes voltage drop, ensuring optimal light performance.

Installing The Switch And Controller

  • Choose an accessible location:
    • Mount the switch or controller within easy reach of the operator, ensuring quick and convenient access when needed.
    • Avoid placing the switch or controller where it may interfere with other vehicle controls or be prone to accidental activation.
  • Connect to the wiring harness:
    • Follow the manufacturer's wiring diagram to properly connect the switch or controller to your wiring harness.
    • Use soldered or crimped connections for reliable, long-lasting performance.

Mounting the Lights

With your lights wired and connected, it's time to mount them securely to your vehicle. This process involves following the manufacturer's instructions, using appropriate hardware and brackets, ensuring a secure and level installation, and applying thread locker and sealant as needed.

Following Manufacturer's Instructions

Always refer to the provided installation manual and adhere to any specific guidelines or recommendations from the manufacturer. This will ensure that you are using the correct methods and hardware for your specific lights.

Using Appropriate Hardware And Brackets

Select corrosion-resistant, high-strength fasteners that are compatible with your light's mounting holes and vehicle's surface. Using the proper hardware will ensure a secure and long-lasting installation.

Ensuring Secure And Level Installation

As you mount each light, take care to tighten the fasteners to the specified torque. This will prevent the lights from coming loose due to vibration or impact. Additionally, check the alignment and stability of the mounted lights to ensure they are level and properly oriented.
