Review on EMylo Smart RF Relay Switch With Wireless Remote Control - DC 12V 433Mhz Relay Module For Home Automation - Set Of 2 Transmitters - 1-Channel - 1 Pack by Kenny Noel

The only ceiling light for the bed of my trailer was over the bed and it required getting on the bed to turn the light switch. I installed this into the hole of where the wires come down for the light and with the two remotes it is now so convenient. This is the 1 channel with 2 remotes. I liked that it came with the wires and clamp on connectors, and that it has a wider range of input DC voltage. The current draw on standby mode with the light off is 82ma. So it is not that much of a drain on the battery. The A button is for on, and the B button is for off. Works great. Would buy again.
