Alright i've tried posting this in the lighting forum to no avail, Both my HID went out at the same time, i recently just had my ballest go out on the right side i replaced that along with 2 new HID Bulbs (10000k) A bit much yes and may be the source of the problem im not sure. I drove the car saterday night with both working i parked the car for the night with both still on i get in the car sunday night and neigher will turn on. (Fog lights and high Beams still work) Check all Fuses both inside the car and the fuse box infront of the battery compartment and in the IPDM (intelligent power distribution module) checked all fuses and relays there and all were good, Went to the infiniti dealership for advice on what the problem may be and they said may of melted my wires (Highly doubt due to both lights going out at the same time) Still checked it and all good. The only place where both of the headlights connect to is the IPDM and everything there seems to be fine, any advice? or suggestions would be appreatied i am completley lost on what the problem may be
