Wayne, is it possible that the bulb is dual element? Although I have separate low and high beam lights, it is aggravating that when I put the high beams on the low beams go off, I checked my cars and when the high beam goes on, the low beam stays on.
When I installed the Silverstar Ultra's, I saw that the life expectancy is only 300 hrs - Dah! As a life extender, when using lights in the daytime, I plan on using the running lights with the fog lights on.
