Particulates from air pollution can rest on the glass of your headlight and over time cause the glass to go foggy. To protect the longevity of your Jeep headlight, invest in a Jeep headlight cover from 4WD. All your favorite off-road brands have headlight covers with their logo on them including KC HiLiTES, Rigid Industries and Hella. Made of material that's UV and weather resistant, a headlight cover will extend the glass life of your headlight. You can also check out the shaded hard headlight covers from 4WD to give your Jeep that custom blackout look.
