2. What's in the Box
Upon opening the package, verify that all components are present and undamaged:
- LED light strip (1 pack)
Note: The product is designed as a single pack. If you purchased a multi-pack, ensure all individual light strips are included.
3. Setup and Installation
Follow these steps for proper installation of your Winzwon Interior LED Car Lights:
- Prepare the Surface: Identify the desired installation locations within your car's interior (e.g., under dashboard, under seats). Ensure these surfaces are clean, dry, and free of dust or debris. Use an alcohol pad if necessary, and allow it to air dry completely.
- Position the Light Strips: The LED light strips are flexible and designed to fit into gaps. Carefully plan the routing of the cables to ensure they are discreet and do not interfere with vehicle operation.
- Secure the Strips: Remove the adhesive backing from the light strips. Press firmly to ensure a secure and even attachment. Avoid tearing the light strip multiple times, as this can reduce the adhesive's effectiveness. For areas where adhesive might not be sufficient (e.g., uneven surfaces), small zip ties can be used to secure the strips.
- Connect to Power: Plug the USB cable into an available USB port in your vehicle. Ensure the USB port and adapter are clean and undamaged before use.
