Remote controled flashlight.

[gadagain]

I would like to make my maglite works with a remote control (turn on and off at distance), without using wires

I Just found this: http://www.cabelas.com/cabelas/en/t...d+light&Ntx=mode+matchallpartial&N=4887&Nty=1

Any one knows about the circuit that goes inside to make something like that?

Thanks in advance.
