·We can prioritize the following methods to check that the car LED high and low beam lights do not light up.
·Step 1: We can interchange the left and right lights to rule out the possibility of the fuse damage, and then exchange the drivers of the high and low beams to confirm whether it can be bright. After doing this, if you find that the driver is broken, you can directly contact to customer service staff of the original sales shop.
·Step 2: If the driver is OK, we can check whether the needle in the plug of wire harness assembly is withdrawn. If yes, you can directly contact the customer service staff of the original sales shop to replace the plug.
