Possible solutions: 1) return it, 2) don’t have a light bulb in the garage door opener, 3) splice the wiring between the bulb and the sending unit so that the door opener activates both the bulb and the laser, 4) plug the laser into the unused half of the duplex outlet that serves the door opener. I chose option 4.
