I have had a set of spencer 35w 6k hid's now for about 3 years and they have worked flawless. I noticed the other day it was starting to rain so I flipped on my headlights and no right headlight. Left is on and no problem. Pop the hood every thing is plugged in fine, no exposed wires, etc. That night about 9pm I go out to check and start the car and the both lights pop on. Turn them on/off several times. Everythings on. Come to the conclusion they only work at night, right headlight out during the day. Any ideas? Appreciate any help.
