This TriOptic™ Lens Kit for D3 driving 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 blocking blue frequencies from the light, which reflect off water vapor and decrease vision. Choose amber to match your OEM turn signals or Selective Yellow for even more d aytime visibility to oncoming traffic . The kit includes two spot lenses and two True-Hybrid™ lenses. Use two spots for maximum distance, two Hybrid lenses for a 50/50 True-Hybrid™ or one of each to create a Spot-Hybrid that adds some additional close range fill while maintaining distance.
