RR headlights

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.

Bulbs are all theoretically made in an identical way, to an identical
design that includes some "design life" specification, so it's not
overly strange that they blew at much the same time.

It's the alarm that's being kept awake by something (see earlier
threads on this in this group for likely suspects), drawing
something like 500mA all the time instead if a tiny raction
of that when in "sleep" mode.

Sorry if its already been suggested

Have you checked the Air Con relays,

A faulty Air con relay flattened the battery on my SAAB 9000
