These LED strips add to a vehicle's custom styling, as well as the vehicle's visibility to other drivers on the road. High-powered Nichia brand LEDs are embedded in a custom molded heavy-duty aluminum strip for extra strength. Housings use 3M adhesive to securely attach directly to the headlight housing. Each light strip includes 5' of wire to easily connect these lights to your daytime running lights or low beams. Dayliner G3 models have more LEDs tightly spaced to create the appearance of a solid line of light.
