Important Notes

Professional installation recommended.
Test tail lights and wiring prior to installation.

Overview:

Our Bushdoof Plug & Play Tail Lights for the Nissan GU Y61 Series 4 Patrol are a full LED replacement for the factory units. On Patrols fitted with functional factory tail lights, the left-hand side plugs straight in and the right-hand side picks up its inputs from the left. Please note that many Australian-delivered Patrols (most often DX and ST models) left the factory without functional tail lights, running rear-bar mounted lights only. If that is your vehicle, you will simply run power up to the tail lights yourself (covered below).

What you'll need:

  • Phillips screwdriver
  • Trim removal tools (if required)
  • Socket set
  • Electrical tape
  • Zip ties
  • 5-core trailer wire (only if your Patrol has no factory tail wiring)
  • Wire strippers and crimp connectors or solder (only if wiring manually)
  • Multimeter (optional)

Wire Colour Reference

  • Green - Park light and start-up animation
  • Yellow - Indicator
  • Red - Brake
  • White - Reverse
  • Grey - Not used

Step 1: Remove Factory Tail Lights

  • Check packaging contents, you should have 2x Bushdoof Tail Lights (Left + Right) and the wiring harness.
  • Access the rear to reach the tail light mounting screws.
  • Remove the screws securing each factory tail light (or rear-bar light).
  • Pull the tail light straight backward to release it.
  • Disconnect the factory plug (if fitted).
  • Ensure no clips, seals, or mounts are damaged during removal.

Step 2: Prepare & Route Wiring

If your Patrol has functional factory tail lights:

  • Plug the left-hand tail light straight into the factory plug.
  • The right-hand side picks up all of its inputs from the left-hand tail light via the supplied harness.
  • Secure the wiring with zip ties, clear of sharp edges and moving parts.

If your Patrol has no factory tail wiring (rear-bar lights only, common on DX and ST):

  • Run a length of 5-core trailer wire up from your trailer plug or rear bumper lights to the tail lights.
  • Match each wire to the colour reference above (green for park and start-up, yellow for indicator, red for brake, white for reverse).
  • Because your inputs come up one side, run a single wire from left to right to carry the indicator across to the other side. Which side you bridge from depends on where you brought your inputs up.
  • Your reverse wire is usually already present, so in most cases you only need to bring up both indicators, brake and park.

Step 3: Install Bushdoof Tail Lights

  • Position the new tail light onto the vehicle and seat it correctly.
  • Reinstall the screws and tighten securely.
  • Ensure the housing sits flush against the body.
  • Repeat for the opposite side.

Step 4: Test

  • Turn the vehicle on and check all lighting functions:
    Tail/Park, Brake, Indicator, Reverse, and Hazard lights.
  • Ensure all functions operate correctly with no dash warnings.
  • Confirm all connections are secure and insulated.
