I think you have the same light as me. I've yet to have a bulb go out but I did have a problem with my first bulb getting so hot on high beam that it burned the reflective coating off of part of it. I bought it from eastern performance and I asked their cust svc. about it and they sent me a new bulb out right away and I've had no problems since. But I almost never run the high beam now. Only at night and only for short periods of time. So, Auto Zone stocks a bulb that will fit? That's good to know.

 

Ya auto zone has several bulbs that will fit.

When we went to the Dragon in June a buddys low beam went out at night a few miles from the hotel (had about 1500 miles on the Cobra bulb he has same light). The next morning on the way to the dragon his high beam went out so had to stop at auto zone and replace it.

 

Our Auto Zones aren't carrying the H4 bulbs anymore. I went with a PIAA antivibration H4. It was $48 but if it lasts, I'm ahead of the game!
