I was thinking about buying something like the Garage Door Butler - or one of about 20 different similar auto-closing devices - though the GDB has one nice extra feature - auto-close in darkness (night) that's very useful as we have gone to bed several times and left the door open over the years.

BUT, I worry about these things malfunctioning and actually opening the door when we're away - or closing at undesirable times - and they all seem to have really annoying beeps and erratic behaviors.

What we really WANT is a full strength light bulb in the house to be ON when the door is open. Not just a tiny little LED - (there's tons of those out there in wireless monitors)

The electronics seem very simple - wired magnetic or optical sensor, hard wired to an A/C switched outlet/bulb or D/C light of some kind. That way when we go to bed the light cannot be missed.

Anyone know of such a thing?
