This TriOptic™ lens kit for D4 lights is designed to maximize visibility in foggy and rainy conditions. The amber and selective yellow lens colors increase visibility in fog and rain by blocking the blue frequencies of light, which reflect off water vapor and reduce visibility.

Choose amber to match your OEM turn signals, or selective yellow for even greater visibility at all times in oncoming traffic. 

The kit includes two spot lenses and two True-Hybrid™ lenses. Use two spot lenses for maximum distance, two hybrid lenses for a 50/50 True-Hybrid™, or one of each to create a Spot-Hybrid that adds extra short-range fill while maintaining distance.
