Cool. How would I use that? It's kind of large. I'm guessing I'd have to gut it and set the switch to 3V then make the connection from one of the car's 12V power wires to the 3V battery receptacle on the garage door opener then just connect the same 12 power wire from the car to the 12V LED on the power switch to get the illumination.

Would a power wire going to one of the power door locks or window switches work with this?
