I fixed the yellow strobe light from the forklift.
The xenon flash tube was burned out. It's the exact same one they carry at Radio Shack, so getting a new one was no problem.
I soldered it in and put it all back together. Now I have a yellow flasher that will run on any 12-80 volts DC power supply.
Maybe I can put it in the back of the electric car to warn people how slow I am going.
