Hi! I am trying to wire 2 led lights in the grill of my car, but I rather not go through the firewall to my controller on my dash. I was thinking that I could do a wirelessly controlled relay. Apply 5v from my controller to a transmitter which connects to a receiver that trips at 5v and closes the 12v relay. I cannot find for the life of me a good solution for this that does not use a keychain or another remote. Any suggestions would be much appreciated!
