The starting voltage is 13 V +, and the flameout voltage is lower than 12.5 V (if it is higher than this value, it will be extended for a few minutes until the voltage.) 2. 1 pair of daytime running lights total power not more than 18 W (most of the daily running lights will not exceed the total power) Wiring Instruction: 1. First connect the positive and negative side of the daytime running lights on the left and right, and connect the negative poles first. 2. Connect the red and black wires of the input with fuse on the controller to light the positive and negative poles of the battery, and the red and black terminals of the output to light the positive and negative poles of the daytime running lights. 3. Connect the yellow line on the controller to the positive pole of the headlight (or reading lamp).

Note: After the battery is connected, the daytime running lights will turn on for about 15 seconds and then the light off. This is a normal phenomenon (realize the delay function). After that, you must start the car. When the voltage reaches 13 V +, it will start working!
