I have a 93 ls and none of her headlights will come on, only my fog lights and turn lights. Is it possible for all my lights to go out at once? Just curious if anyone has this experience before I tear into the front of my car. Also they are xenon. Thank you.

May try plugging a halogen into the factory harness and see. Generally I would say the ballast has gone south and or the added wiring to hook them up has a break. I presume they were working fine prior? Any changes recently?
