I have the jdm hid headlights and when they are on and I hit the high beams one of the city lights goes off. If I have the fog lights on the foglight goes off as well. This only happens on one side, do any of you know what could be causing this?

 

sounds like a wiring issue. check to make sure everything is plugged in correctly. a grounding issue maybe?

 

Def. a wiring issue, but I am not familiar with the wiring for the JDM headlights at all, sorry man.
