After putting on side skirts at night, I turned on the car/lights only to see that my passenger HID is not working. After flickering the switch a few times, it will work but the times it doesn't, the ballast will make a buzzing sound for a short second. Also, when I start the engine, the passenger light that was previously on will shut off. It seems like I would haft to be lucky (after 4-5 tries) in order to have both the HID headlight on when igniting the engine. Now I am still learning on cars and a bit newbie with this stuff. Tomorrow I will switch the HIDs out and see if it is the Bulb, ballast, or relay.
