I always wondered what the 1003/3t22 hi-lo flashers were primarily used for.
I always thought they had to come from some other application and that they weren't used only for sirens.
Look familiar....

Duh.... A flasher for signs....
I'm going to call them and see how much the stupid things cost.
Probably a fortune...
