Hey guys,

The side of my house is totally visible to the cul-de-sac in my neighborhood. I have a side door to my garage that's visible there with a light fixture which I typically leave on. It illuminates the street and helps add an extra bit of safety to the cul-de-sac. Although I've got a compact flourescent in there, I would prefer to not leave the light on 24/7. Ideally, I would like to have a light sensor which turns it on only when it gets dark, and turns it off when it gets light.

Do they sell anything like this that I can incorporate into my existing wiring? Everything I see seems to be built into a light fixture, but I prefer to use the one I have.
