Finicky, expensive headlight on Volvo XC90

Maintenance/Repairs

I have been having intermittent issues with the driver’s side headlight. It will randomly fail for no reason while driving. This can often be remedied by turning the lights off and then back on again. The headlight will also fail not-so-randomly. Two triggers are driving on a bumpy road (we never get potholes in the winter in Ohio), and - here could be the clue to the problem - when I make sharp left-hand turns (90 degrees). What could cause the headlight to fail by making a left turn? The ballast has already been replaced once under warranty (which has since lapsed), and the dealer has wanted to replace the bulb since the xenon bulbs are quite expensive, and may not actually be the cause of the problem. I’m stumped, so I figured I’d turn to my last resort - you guys! Any insights?
