I have a garage 120 V overhead light connected to a light switch at the entrance. When the garage door opener engages, another 120 V light on the opener lights up but that light with one bulb is quite dim for the large garage. I would like to take the wires from the garage door opener light and connect them in parallel to the overhead light in the garage.
In that way, the overhead light would turn on either via the switch at the entrance or when the garage door engages. Will that work, and what happens if the light switch is on AND the garage door engages at the same time?
