Do they burn out like regular headlights? Are they covered under warrenty?

Not usually, yes

My ballast went before the bulb did.

The bulbs have an estimated 2600 hour lifespan. How many hours on your ballast?

I'm considering a used set of Lltek 2pc Xenons for my car, which are probably a few years old and working well now.

I have heard that often enough, however, that if anything goes, it is usually the ballasts before the bulb. I don't know if it is the same for the
A4, but this represents a pain for an A6. The bumper has to be dropped, in order to clear the Xenon housing out of it's enclosure.
