Jim, I checked the LF for play that might let the bulb move around & compared it to the RF & I didn't see anything that would allow the bulb to vibrate. Maybe what I need is one of those $1,000 (or $10,000) NASA Space Shuttle Heavy Duty headlight bulbs.
Since the Powers That Be want to shut the program down
maybe they will have a spare laying around I can buy at the going out of business sale.
Dan, I looked at the socket & wires going to the LF headlight & I didn't see any corrosion. There isn't much exposed wiring to the headlight before it goes into the wiring loom. I'm surprised
that the headlight wiring isn't a heavier gauge wire. It seems like it's a lighter gauge wire than the old sealed beams used.
Carson, some of the first CFLs I installed didn't have a very long life either. Then when the CFLs die you can't just chuck them in the trash because of mercury. Is that progress? It's been better lately but to make them cost effective they've got to last a whole lot longer than the traditional incandescent. Stay
Thanks for your replies. I guess I'll just keep a spare in the tool box.
