Look into a CANBUS Relay harness. I wouldn't personally recommend plug and play LED or HID lights. 99% of the time they don't offer "Better" light.
I am retrofitting some LED projectors into my headlights and had a flickering issue. These are OEM LEDs and drivers so they are quality. The flickering is not an issue of quality with the LEDs it's an issue with the WK lighting system. I bought this Mopar Spec Low Beam harness. Should be here tomorrow and hopefully solve my issues.
