Got the left DRL malfunction. I went to replace the bulb, which are the GP Thunder H8 35W I have been running for two years, and the left socket is completely burned out. My question is, can I just replace the socket, or the wiring harness needs to be replaced as well? Does anyone know the part # for the socket?

 

You can not buy only the socket. It is part of headlight.
Maybe you can find a broken headlight and pull out that socket from it.

 

Are you kidding me? I thought this would be a simple fix.

 

With all brands is the same. You can not just buy the socket that is in the headlight.
