I've got JK tail lights on mine, had considered WK tails but the JKs fit the truck better to my eye and my budget. Once I had trouble finding a decent set of MJ lights, I knew I didn't want to do it twice. I'll probably sell my MJ lamps eventually, but for now they're in a box.Did you build adapter plates to install them?Yes, similar to the guys who have installed LEDs. The width on the JK lamp is nearly identical to the MJ lamp, but it isn't as tall or deep. I did it mostly for the availability of the JK lamps, I wasn't disappointed with the visual style of the MJ lamp.
