garage door open light
I will say that the project is easier said than done.
They make switches with a little bracket to turn them on and off, but you need to find one that is rugged and waterproof. Also you may need to customize the way it is mounted to the garage door frame and there may be a lot of mechanical tweaking involved to get it to work right and stay in place.
Although many switches of this kind work on 120 volts, using low voltage helps because it may be difficult to shield the otherwise exposed connections.
Is it practical to install a "car rear view" type mirror on the side of the house that gives a view of the garage door? No electricity, no moving parts.
