Regarding installation, since the plastic parts of the original lamp cup buckle are relatively hard, it is recommended to use a hair dryer to soften the buckle position before installation.
Please remove the white terminal of the light before drilling the hole, so that a smaller hole can be opened to complete the wiring.
After the wire passes through, reinstall the terminal. Refer to the last picture of the product details for wiring and plug it in the corresponding position. After connecting, control it through the ch6 button on the remote control.
Since the ch6 control button needs to control multiple groups of lights. It takes several more presses to control this group of roof lights. Finally, tie the wires with a cable tie to complete the installation.
