[QUOTE="Chris, post: 425342, member: 1"] It's the LED headlight feature. Later model JKs had the option of LED headlights from the factory. In order to get around the flickering caused by LEDs and the CANBUS system, Jeep added a parameter in the PCM that would allow the dealers to enable it for LED headlights. Once enabled, the flickering goes away. I added the factory Mopar LED headlights to my JK (it came with halogens), which then caused the annoying flicker. I used the J-Scan app to enable enable the LED headlight option, and the flicker went away! HIDs wouldn't need it, as they don't run of super low voltage like LEDs do. [/QUOTE]
