2. Safety & Warnings
- Professional Installation Recommended: Only professional personnel are allowed to install and debug this product. It is strictly prohibited to modify internal circuits or light sources without authorization.
- Compatibility Check: This product is only applicable to the corresponding vehicle model. Before installation, ensure to check your vehicle's model, year, and configuration to avoid mismatch.
- Avoid Damage: Do not scratch the surface of the lamp assembly with sharp objects to prevent affecting light transmission. Avoid using high-pressure water guns to directly flush the controller interface when washing the car.
- Outdoor Use: If used in an outdoor application, confirm that the seal is intact to avoid damage from water accumulation. Keep away from sources of fire and corrosive environments.
- Children Safety: Keep the device and its cord out of reach of children under 3 years old.
- Long-Term Parking: If the vehicle is parked for more than 15 days, it is recommended to disconnect the power supply of the controller to prevent minor power consumption from affecting battery life.
3. Setup & Installation
Before beginning, ensure your vehicle's ignition is off and the interior lights are switched off.
- Prepare Tools: Use the provided plastic pry tool or a similar non-marring tool to gently pry open the existing light covers.
- Remove Old Bulb: Carefully remove the old halogen bulb from its socket. Be cautious as the bulb may be hot if recently used.
- Insert New LED Bulb: Connect the new LED bulb directly to the corresponding socket. Ensure a secure fit. If the LED does not light up, remove it, rotate it 180 degrees, and reinsert it (LEDs are polarity sensitive).
- Test Light: Briefly turn on the interior lights to confirm the new LED bulb is functioning correctly.
- Replace Cover: Carefully snap the light cover back into place.
- Repeat: Follow these steps for all other interior lights you wish to upgrade.
Important Note: Before first use, it is recommended to activate the ambient lighting function in the "Vehicle Settings - Lights" section of your car's central control screen. Some models may require a synchronous upgrade of the car's infotainment system to the latest version for full functionality.
