Can anyone point me towards a product or guide to make two key fobs that when pressed, turn on a light in the other? Answered

I'm working on a little project that would require a very, very small transmitter/receiver combo, that needs to be both small and battery operated on 1 channel. I seem to remember some product that did something like this, kind of a secret message toy or something to that extent where when the button was pushed on one it would turn the light on in the other, so you could signal each other from across the room or something to that extent. I really just need a micro micro receiver that's linked to a 1 button key fob remote. If anyone can point me towards that product or a kit or what have you, lemme know! thanks!
