I have the OEM fog lights and i took out the bulbs becuase i wanted to put hyper white bulbs on both my head lights and fog lights but when i took them out i noticed the its H11 and i have to found any replacements for the H11 so i'm wondering if anyone has found any PIAA bulbs or any other company that has H11's or my other plan would be to change the wire harness.....Has anyone done that and what can go wrong if i do, do that.
