The all-new XB Evo headlights are a showcase of everything Morimoto is made of. Packed with features that demonstrate a true attention to detail including the latest in technology, compliance, quality, and styling, these headlights are designed for enthusiasts who are serious about all the above, even if it comes at a premium. Our patent-pending heating system warms the surface temperature of the headlight lens to minimize frost buildup when driving through wet and snowy conditions in the wintertime. The signal swap system allows users to personalize how the daytime running lights and turn signals operate according to personal preference, all through a simple plug n play key on the back of each headlight. The daytime running light can be configured to run full-time in either white or amber with no compromise in intensity either way. When starting your Ram, the optics will automatically illuminate in a multi-stage sequence before turning back off. XB Evo headlights aren't cheap, but they are built to a high standard and should easily last the life of your truck! We're proud to stand behind the product with an industry-leading five-year warranty.
