I just installed some. You need to make sure that they come with the right cable adapter for the JL, different then the JK. And you need to get the Headlight bracket adapter for a standard 7" headlight. Dont waste your money on expensive ones.
I have the inspired engineering Halo set with adapters. And I am very happy with them, install was simple, and they get alot of compliments, even from the sales guys at the dealership when my wife drops off her Challenger.
