Take them off and see if it goes back up.

I think that you just got complacent and started being a little bit more mean. Meanie.

Huge difference in drag. The WJ is a pretty aerodynamic vehicle, much of that because of the nice smooth transition between the windshield and the roof. You are basically ruining that with your roof lights, and creating a huge amount of turbulence and drag. Try moving the lights to the bumper.
