One point to make is the 4 light law. I have known about this for years as well. But please remember the Cherokee already breaks that law with 6. DRLs, head lights and fog lights. So I guess they got a pass on that.
To the OP, do you have voltage leak using the factory fog light switch? In my 2012 Ram I installed Rigid LEDs and wired a set into the factory fog light switch. I had to put them on their own switch. The lights blinked like construction lights. Other guys had the same issue. The electrical switch did not really open and would have gotten me a fine. I would love to do this mod but want to make sure that you wiring the D2s directly to the factory wiring did not result in voltage leak.
