This TriOptic™ Lens Kit for D2 lights is designed to maximize visibility in foggy and rainy conditions. Both Amber and Selective Yellow lens colors increase visibility in fog and rain by reducing blue frequencies that can reflect off water vapor and reduce visibility. Choose Amber to match your OEM turn signals, or Selective Yellow for even more daytime visibility to oncoming traffic. The kit includes two spot lenses and two flood lenses. Use two spots for maximum distance, two floods for maximum spread, or one of each to create a 50/50 True-Hybrid that combines the best of both worlds. What’s In The Box?
