I have an h.i.d kit..Both transformers work...but for some reason i can only get power to the right ( passenger side) headlight. Both side ( blinker lights) work, just not the HID bulb on the driver side. Can anybody maybe run me through some possibilties of problems or solutions. thanks

 

to start they are ballasts.
same thing happen to me switch the ballast to the opposite side to see if it is bad.

 

ballasts my bad.. Ya i tried that and they both work, it just doesnt work on my drivers side.
