We just replaced our outside light fixtures and there are a few I would like to have motion activated. The front door to make it easier to unlock the door, the two on the front of the house that are on a timer, currently. Id like to keep that feature but also have them kick on due to motion. And the side yard light. Its currently on a switch inside the garage and I always forget to turn it on or just decided to go without it since im too lazy to walk around to turn it on and off. will these "ad a motion" kits work for these applications? I went to lowes and they dont have a matching fixture with built in motion. Anybody been down this road?
