It might also be the ballast. Switch the bulb from the good headlight and see if it stays on. If so it's the bulb, if not it's the ballast. Wear latex gloves, the oil from your skin will damage the bulb.

I think you need D2S Xenon bulbes but if it goes on and off it sound like bad/lose/weak conatct or even balast which is most expensive. They are alse sensitive on voltage input but you would noticed if you have bad batery or alternator on other thing too.
Good luck

Sometime the easy route is the best route. This would have taken 5 minutes with a call to the dealer. Now it's 24 hours later? Doesn't make much sense to me

I dont know PN but i think you can use any of them even from some other vehicle type. They have same conectors and work under same voltage. Got bunch of them on eBay
