I had a similar thing with my Mom's car, was blowing bulbs at a rapid
rate. Two things were the problem. First, I was using a discount brand
of bulb. Dad got some real ones, which worked better. Second, the
ground connection wasn't quite touching the bulb. I had to put a bit
of electrical tape on the other side of the bulb to force it over a
bit, so it would touch the ground connection more firmly.
