Note:
After connecting the battery, the daytime running light lights up for about 15 seconds and then turns off the light. This is a normal phenomenon (realising the delay function). After that, you need to start the car. When the voltage reaches 13 V +, it starts to work!
Wiring instructions:
1. First connect the positive and negative side of the daytime running light left and right and connect the negative pole first.
2. Connect the red and black cables of the input terminal to the fuse on the controller to the positive and negative pole of the battery and the red and black cables of the output terminal to the positive and negative pole of the daytime running light
