This TriOptic™ Lens Kit for DM lights is designed to maximize visibility in foggy and rainy conditions. Both Amber & Selective yellow lens colors increases visibility in fog and rain by blocking blue frequencies from the light which reflect off water vapor and decrease vision. 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.
