Hi guys, i have a problem with my headlight bulbs, i bought a pair of 5000k bulbs from ebay ( this is probably the problem lol ) and when i turn the lights on the bulbs flick on then straight back of again, sometimes only one sometimes both,
if i repeatedly switch them on/off/on they do stay on and work fine, then after a spell of use if i turn them of then back on they work fine??
is this possably a starter issue or ballast or just shoite bulbs?
the car is a pre-facelift S3 with OEM hid lights.
