Nilight Magnetic LED Trailer Towing Light Kit (Model TR-143)

Instruction Manual

1. Introduction

Thank you for choosing the Nilight Magnetic LED Trailer Towing Light Kit. This kit provides essential lighting for safe towing, including tail, stop, amber turn signal, and license plate lights. Designed for ease of use and durability, it features strong magnetic mounts and an IP68 waterproof rating.

This manual provides detailed instructions for proper installation, operation, and maintenance to ensure optimal performance and longevity of your light kit.

2. Safety Information

  • Compatibility: This light kit is suitable for vehicles with 5-wire tail light systems only (with turn signals and brake light separated). It will not function correctly with 4-wire tail light systems (e.g., some 2005 Nissan Frontier 4x4 nismo, 2001 Ford F550), where the brake light may illuminate in amber instead of red. Always double-check your trailer wiring plug connector before installation.
  • Secure Mounting: The lights come with strong magnets for quick attachment. Ensure the magnets are fully attached to a clean, flat metal surface on your vehicle or trailer to prevent detachment during travel, especially on bumpy roads.
  • Electrical Connection: Ensure the 7-pin plug is securely inserted into your towing vehicle's existing 7-way trailer plug. Improper connection can lead to malfunction.
  • Waterproof Rating: The lights are IP68 rated, meaning they are entirely submersible and sealed against water and dust. However, ensure all connections are dry and secure before submersion.

3. Product Features

  • 5-Wire System Compatibility: Designed specifically for vehicles with separate turn signal and brake light wiring.
  • Multi-Functionality: Provides tail light, stop/brake light, rear position, direction indicator (amber turn signal), reflector, and license plate light (right light does not include license plate light).
  • High Brightness LEDs: Left lamp features 16 diodes (5 for left turn signal, 5 for tail light, 6 for license plate light). Right lamp features 10 diodes (5 for right turn signal, 5 for tail light). LEDs draw less amperage while providing optimal brightness and a longer lifespan.
  • DOT Compliance: Ensures safety and meets regulatory standards.
  • IP68 Submersible: Fully waterproof and dustproof, suitable for all weather conditions and submersible applications.
  • Magnetic Mounting: Equipped with two strong magnets per light for quick and easy attachment and removal.
  • Extended Cable Length: Includes a 24ft cable from the lamps to the 7-pin plug, allowing flexible placement.

  • 2 x Magnetic LED Trailer Towing Lights

5. Installation

  1. Verify Vehicle Wiring System: Confirm your towing vehicle has a 5-wire tail light system. This kit is not compatible with 4-wire systems.
  2. Connect the 7-Pin Plug: Insert the standard 7-pin plug of the light kit into your towing vehicle's existing 7-way trailer plug. Ensure a secure connection.
  3. Route the Cable: Carefully route the 24ft cable along your trailer or vehicle, ensuring it is clear of moving parts, sharp edges, and hot surfaces. Use cable ties (not included) to secure the cable if necessary.
  4. Position the Lights: Place the magnetic lights at the rear of your trailer or vehicle. Ensure the magnets are firmly attached to a clean, flat, metallic surface. The left lamp includes the license plate light function.

6. Operation

Once installed, the light kit will synchronize with your vehicle's lighting system to provide the following functions:

  • Tail Lights: Illuminate when your vehicle's headlights or parking lights are on.
  • Stop/Brake Lights: Brighten when the brake pedal is pressed.
  • Turn Signals: Flash amber when the left or right turn signal is activated.
  • License Plate Light: The left lamp includes a dedicated light for illuminating the license plate.

7. Maintenance

  • Cleaning: Clean the light lenses periodically with a soft cloth and mild soap to maintain optimal brightness.
  • Connection Check: Regularly inspect the 7-pin plug and cable for any signs of wear, corrosion, or damage. Ensure connections remain secure.
  • Magnetic Adhesion: Before each use, verify that the magnetic lights are securely attached to the vehicle or trailer surface. Clean the mounting surface if necessary to ensure strong adhesion.
  • Water Resistance: The IP68 rating ensures the internal LEDs and circuit board are fully sealed. No specific internal maintenance is required for water protection.

8. Troubleshooting

  • Lights Not Working:
    • Check the 7-pin plug connection to ensure it is fully seated and free of corrosion.
    • Verify your vehicle's tail light system is a 5-wire setup. This kit is not compatible with 4-wire systems.
    • Inspect the cable for any visible damage or breaks.
  • Incorrect Light Function (e.g., amber brake light on 4-wire system):
    • This indicates incompatibility with a 4-wire system. Ensure your vehicle has a 5-wire system for proper operation.
  • Lights Detaching:
    • Ensure the mounting surface is clean, dry, and flat metal.
    • Confirm the magnets are fully engaged with the surface.
