Perhaps they're trying to tell you something. Have you checked that the
voltage regulator is not spiking significantly over 14V? Just a thought.

Thanks, Bob, but I think the only thing those bulbs were trying to tell
me was "We're junk!"

It's stunning (to me, anyway) that GE continues to successfully market
a landing light bulb with a 25 hour design-life. (The 4509)

I'll bet they laugh every time they sell one.
