- Secure New Light: Use the factory screws to tighten and secure the new light.
Important Note:
It is highly recommended to use the original factory screws for a perfect fit. Use a hand screwdriver tool for installation. Electronic tools can often overtighten screws, which may cause the light casing to crack easily.

5. Operating Instructions
The Nilight Third Brake Light functions automatically with your vehicle's electrical system. It integrates three primary lighting functions:
- Brake Light: The 3 red LEDs illuminate brightly when the brake pedal is pressed, providing a clear signal to following vehicles.
- Cargo Light: The 12 white LEDs provide illumination for the truck bed, useful for loading, unloading, or working in low-light conditions. This function is typically activated via an interior switch in your vehicle.
- Reverse Light: The white LEDs also function as reverse lights, illuminating when the vehicle is shifted into reverse, aiding visibility during backing maneuvers.

6. Maintenance
The Nilight Third Brake Light is designed for minimal maintenance due to its durable construction and LED technology. To ensure optimal performance and longevity:
- Regular Cleaning: Periodically clean the lens with a soft cloth and mild soap solution to remove dirt and debris that may obstruct light output. Avoid abrasive cleaners.
- Inspect Seal: Although the unit is IP67 waterproof, it is good practice to occasionally inspect the foam seal around the light for any signs of damage or wear, especially after extreme weather conditions.
- Check Connections: Ensure the electrical connection remains secure and free from corrosion.
The LED light source is designed for a long lifespan and does not require bulb replacement.
