5. Installation Guide
The Car Door Light features a simple, wireless installation process.
- Prepare the Surface: Choose a flat, clean area on the inside of your car door where the light will be installed. Ensure the surface is free of dust, grease, and moisture.
- Attach the Base: Peel off the protective film from one side of the double-sided adhesive. Apply it firmly to the back of the light's base.
- Mount the Base: Peel off the remaining protective film from the adhesive on the base. Carefully position the base on the chosen area of your car door and press firmly for several seconds to ensure a secure bond.
Figure 2: Applying double-sided adhesive to the light's base. - Align the Sensor: Identify the infrared sensing area on the light unit (refer to Figure 1). When the car door is closed, the infrared induction paper sticker must coincide with this sensing area to ensure proper automatic on/off functionality. Attach the infrared induction paper sticker to the car frame, opposite the sensor, so it aligns when the door is closed.
