Very true. I've seen several bulbs shattered, probably due to a hot bulb being dunked in cold water.
I always unplug the trailer lights after arriving in the lot, and allow them to cool (assuming they heated up) while removing tie-downs, mounting the radio, and loading the dive gear. Just gotta remember to reconnect them before taking off again.
None the less, I always carry a complete light change, spare bulbs and crimping tools in my truck when I am heading away someplace. In my experience, the odds of a light failure increases directly with the distance from home...
I've got bulbs, but figure an emergency repair is wire ends stripped and twisted, and a few wraps of electrical tape. But I did just get a couple of toys: a nifty little refillable butane torch, and a butane soldering iron, so maybe I'll throw a more complete repair kit together. Then again, maybe not...
On the bullet-proof lighting thing, I've got another pet peeve about trailer accessories: Why can't they build a trailer jack that will last more than a year with salt water use? Seems that it should be easy enough; just have to choose materials that, when used near salt water, DON'T CORRODE (emphasis for the benefit of trailer accessory engineers.)
On my previous trailer, the jack got submerged pretty often; it lasted, on average, about 6 months before replacement was mandated (turny bits no longer turned.) The new trailer keeps the jack out of the water, but the jack still only lasted about a year (and that's with occasional tear-down and cleanup and grease loading.)
So, as long as we're dreaming about quality parts, well...
