All the jk's run PWM lights. Your best bet is to trigger them from the factory wiring but use the relay that came with the lights. I went ahead and wired a switch for my HID Hella's since I wanted to be able to use them whenever I wanted. When they're on I can barely tell the headlights are even on they're so bright.
