Over here in Va all the signal lights were converted to led, but the problem is that when it snows, the led does not put out enough heat to melt the snow like the old lamps did.
These look very stylish. Perhaps I'll mount a few to my car fenders, 50-75 atop the airplane wings and a few to my bed posts. If I can find a big enough battery to power it, maybe I could even mount one to a crash helmet and walk around town with it strapped to my head.
