Have a question? I would like to add a light switch to the entrance way going into my garage. I have a existing light switch going from the house to the garage. It would make life a little brighter.
To install a second switch onto an existing light circuit, you'd have to change the other switch and wiring to accommodate what's known as a 3-way switch circuit. If you've got access to the wiring, this isn't an overly difficult thing to do. If you have no access, then you may want to change the switches out to remote switches, then there is no need for new wiring.
