I believe that many car owners have encountered the situation of LED lights burned out, and they directly replaced the lights without thinking too much. But what is unexpected is that it didn’t take long for it to burn again. So, how to solve the problem that the low beam is often burnt? Let's analyze it below.

If the dipped beam often burns, it is probably because the dipped beam relay is abnormal. Why do you say that? To know the function of the low beam relay is to increase the output current of the low beam lamp, so that the luminosity of the low beam lamp becomes brighter. Then, once the low beam relay is abnormal, it will cause the output current of the low beam lamp to be too strong, so that the LED lamp will always burn.

Steps to check the low beam relay:

First of all, we need to check whether the low beam relay is normal, and directly use a multimeter to measure the output line of the flash relay to see if there is a 12v output. If there is an intermittent output change, it means it is normal. If there is no output or the output is always 12v, it means that the near-beam relay has been damaged and needs to be replaced with a new one.
