Can these units be taken apart and wired to a battery pack to get away from the bulk? I build and fly 1/2A civilian planes...pretty thin edges to have to work with. It would be nice to be able to take one apart and just use the LED and whatever else makes it blink (would it be just a blinking LED and a battery case or curcuit board also??) and wire everything down to the AA's?

A nice touch I think I might try would be wiring in high intensity color LED's behind the wingtip strobes for "running lights" between strobe flashes.

I know this is getting away from the convienence of the main idea of the valve stem item, but stumbled on this looking for a simple way to add navigational lights.
