This Truck-Lite Headlight Kit by RIGID includes two headlights and two anti-flicker PWM adaptors which eliminate headlight flicker in 2007-2013 Jeep JK models. A limited number of Jeep JK users may see a flicker as a result of the PWM electrical system used on these vehicle models. This adapter will store power during on-time, and deliver power during off-time, allowing the lamp to receive consistent energy delivery. Compatible with 2007-2013 Jeep JK models.
