Well... They SUCK BIG TIME!!!
LOL...best thing I've found out is buy the bulbs (LED) that has the
battery build in them. I think they run about $60 a bulb but it does
away with all the wires. And no ballast. All it takes is a hot and a nutural. It uses the hot going to the battery. It's usually a different circuit than the 1 to the regular bulbs. Stays not when the switch is off.
