It is a super simple thing to do...but something we are afraid to tackle because...well, let's be honest, it entails messing with electric. And who isn't terrified of electricity. Well, maybe not everyone...maybe just me. I tried to get the electric company to turn the power off in my part of town when I wanted to do some electrical work. They won't do it.
Anywho, light fixtures are easy to change out. If you turn off ALL the little switches in your breaker box it's no biggy. Just make sure you have a flashlight handy!
