Headlight Switch problems of the 2006 Audi A3

Intermittent headlight malfunction. Over the course of a year of ownership, the right headlight has malfunctioned (turned off), with no consistent cause apparent. Just recently the left headlight has started to malfunction as well. While driving both headlights have gone out! this condition is both unsafe, and illegal - as many states will issue a traffic violation for driving with a non-functioning headlight. The right like malfunctions every time I use the lights and the left has malfunctioned 4 times in the past month, the headlight flickers, then goes out, but will come back on when the lights are turned off then on again. But the flickering occurs with in minutes of switching them back on. The dealership has been notified of the problem and has claimed that everything is fine and they can not reproduce. They have suggested I wait until both go out to replace them. No parts have been repaired or replaced, however they have claimed to perform a visual inspection of the electrical connections. Annecdotal evidence (conversational, and via internet owners' forums) suggests that the problem is widespread among a substantial portion of Audi's model range and years.
