2005 Audi A4 - Lights flicker

2005.5 2.0L quattro, xenon headlight issues. Had replaced both once already. Flickering, shuts off. Is there any real cure. Why no recall?

Xenon bulbs have an average life expectancy of 2000 hours in any car.so you are going on your second set in 14 years.

14 year old car for burned out bulbs? Not going to happen.
