Tip: How to detect a circuit as a DC power supply system.
After turning on the vehicle's electrical system, switch to the night light mode. If the lights can be lit without starting the vehicle, it's DC (direct current), and if not, it's AC (alternating current).
All LED headlights sold by our store must be used in a direct current (DC) electrical system. Using them with an alternating current (AC) supply can easily damage the LEDs.
Installation Instructions:
LED headlights have positive and negative poles, if they do not light up after replacement, simply rotate the connector 180 degrees and insert it again.
