The RIGID Anti-Flicker PWM Adaptor eliminates 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 and made to withstand rugged terrain. Electronics are sealed in epoxy to resist damage caused by corrosion and moisture.
