Bump from 2010.....
I've been looking for a reverse light for everyday use that could double as a camp/trailer light. Going through this thread got me inspired so I started on a telescoping mast. I only have an old homemade mtn bike light with a 12v halogen in it for testing. At this point I'm just getting the mast figured out. I'll probably end up goin with a led solstice or dually.
I had an old thrift store tripod sitting in the garage. Took a leg off. It telescopes from ~23"-->~56"
bike light strapped to the mast for testing
The bikelight already had a coiled cord on it. It is light gauge but never had a problem with the halogen at 15w. The led should draw similar.
Taped the cord
To the bottom for testing
Mast extends fully with coiled wire inside the mast 56"
mast extends and detracts perfectly, downtown hang up at all.
I'm mounting this on one side of my spare carrier. jeep is daily driven so I like to keep it realitively stock looking on the outside. Ill mount it on the tailgate behind the spare with the 3d brake light. I figure I can hide it back behind the tire fully collapsed if i don't like the 'hood or have to leave it parked for a long time.
