Interior LED + Reverse backup package?
 

Anybody tried LED light with the backup package? It's only about 30 bucks for all of them. I'm sure there's a DIY somewhere, but has anyone had any problems with installing these at all?

Try reading the countless vendor threads where they sell these, which I'm sure have thousands of posts total. If there were issues people wouldn't be buying them. And maybe support one of our vendors while your at it, instead of a random shop on amazon
