Hey,
I have a 1996 Audi A4 Quattro with aftermarket HID lights. Recently both lights have been randomly flickering, or not turning on at all. Both lights were fine until the weather started getting to below zero. In the last couple days, the left light has stopped working entirely, except for the brights. I bought the car used and was not the one to install the lights. I'm not sure if the last guy installed them properly as there are only two brightness options, normal and brights, instead of the regular daytime, nights, and brights. Any help would be great.

thanks.
