While driving my 2000 RR County yesterday, both low beam headlight bulbs blew out within 3 hours of each other. When I originally changed them, I changed both at the same time. I used Sylvania Silverstar bulbs. I wanted to know if this was common. I kept driving after the first one figuring I had some time to take care of things; obviously I didn't.
My curiosity is since I seem to be having an electrical issue. In an earlier post, I pointed out that the battery completely discharges after
2 weeks of non-use. I have had the alternator, battery and electrical system checked and all are fine.The theory is that something is triggering the main computer to continuously run diag while parked in the garage.
