I want to wire a separate power on indicator light to the ON side of an existing light switch. I'm familiar with how to wire it. The mini light I'm using is rated for 110v and has two extremely small gage pre attached wires. My question is can I connect the small gage wire to existing 12/2 and not cause an issue. I realize there are light switches that have this feature. However, they are not the solution for this application. Please read the below:
My barn has no windows and when the door is closed you cannot tell if the lights were left on. The indicator light would mounted outside so it's visible . The question is will it be safe to connect the small wire gage to 12/2. Yes I could add an outside light. However there are four other separate light circuits and a fan that I wired. Don't want the barn to look like lamps are us. That's the reason for a small light.
