Solar powered lights w/motion activate can be bought at Dollar General for $5.
I have them on my RV (car) Port. They work great.
I have a 1989 Dodge XPLORER RV Class B - Purchased 10/15/10 IN CASH
Fiance' purchased a Class C (B+ ?) 2002 Dynamax Carri-go on 5/1/15 IN CASH
We've got the best of both worlds
