Dog party,
If ure gonna go with the rotating design, I have an idea for the light pivot end.
Instead of coming up with some type of clamp for the light to mount to which pivots, why not mount the light solidly to a normal light tab which is welded to a regular piece of tube, thus rigid. The key would be to have this tube slip inside of a second tube which would actually be the main light bar. Drill 2 holes directly through both bars so the holes line up and put a pin through this. Remove the pin, allow the light to flip down 180 degrees, the holes line up again and the pin goes back in. This would create a solid mount but still give ability to spin the light 180. Another advantage with this is that if u use that springy, curly sheathed wiring which expands (you know, like CB microphone wire) you could even pull the inner bar out entirely and use it for a handheld spotlight!
The pin could be replaced with a nut and bolt for added security. Placing a big rubber grommet on the tube that the light mounts to at the end nearest the light would then squish up against the outer tube adding some tension and keeping water out.
Yeah . . . something like that would work well. The remove it from the swing arm and aim it freely like a flashlight is kinda funny, but could be quite useful . . .
I would only note that more than a single set of holes on the outter swing arm bar would be needed. The bar holding the light only needs one set because it will rotate to line up with varous holes on the outer bar. Because to aim the light downward you would want to rotate it somewhere betwee 0 degrees and 180 degrees. But a series of holes might give enought angles to make it work quite well, even if you put a set of holes every 45 degrees.
Another variation is to go with a single line of wholes like Cacher mentioned to lock in the 0 or 180 degree position, but have a knob that can be used to give a locking tension on any angle between (not to be used for driving at normal speeds). Kinda like an olympic size dumbell set uses to secure the clasp on the end which holds the weights from sliding off of the bar. Basically just a threaded hole with a knob that can tighten or loosen up.
Edit-- Just thought of how to make a threaded hole easy... drill a hole on the outer tube and then weld a nut to the hole . . . using the threads on the nut to tighten or loosen a bolt/knob down on the inner tube to lock the light in position . . .
