Recently my left HID went out on my 04 Coupe and when i was testing different things to see if it was actually the bulb that was broken i put it on the opposite side and it worked so now i have no idea what component is broken. There is some condensation on both headlights so obviously there is leakage causing the problem. There is enough voltage going into the projectors but i have no idea what could be the real problem. Any suggestions or anybody have the same problem?

 

Could be the wiring or the ballast.

 

Its definately not the wiring. The ballast is located on the bottom of the back of the headlight right? the kind of connector box?

 

swap ballast and see if its the wiring or the ballast thats out
