Probably a wonder it lasted as long as it did. I took another bulb of a different type out of another fixture that was sealed and experience the joy of its replacement not working.
I wouldn't mind the rightful owner retrieving that pin. We had some plumbing work done last year. Hopefully they had another pin for their trailer if they lost this one. I'll post an image of what it was carrying in Exhibition.
I found many landscape bulbs looking that way most of the time it was due to water leaking into the fixture or irrigation spraying it when it was hot. At my home LED is all I use and haven’t had to replace any in 5 to 6 years or more.
I’ll guess whoever lived there before had a lawn tractor and trailer and at some point lost the hitch pin. CRL to the rescue, or the cheaper option is the trash can. Paul
Paul has it. I found the pin a few weeks ago and have no idea whose it was or how long it was there. The bulb was actually used in a landscape lighting fixture (we're switching to LEDs as the halogens/incandescents burn out). The rock is, well, just a big rock that sits in our front yard.
Both are, or were, the height of their then technologies....a turn indicator bulb, I believe, and a latch pinion key...probably a century apart in manufacture. Traveller
