I think those lights are gonna make you nuts though... They're motion sensors, so I think they'll be turning off and on a lot all night when cars go by at the store. Hopefully you can rig them to just stay on, and the one on the porch too. That's what I'd want anyhow.
Looks like there are some switches on the bottom...maybe there's a way to set them so they come on as soon as it gets dark.
Glad they're there, in any case, even if they do go on and off at night!
