- EAGLE LIGHTS QUALITY - The DOT approved Eagle Lights SL4627B 4 x 6 LED headlight is constructed with a heat treated die-cast aluminum body and a high quality polycarbonate shell with a textured finish for extra durability. Powered by high output LEDs, the SL4627B is the best and brightest 4” x 6" LED headlight available.
- MULTI-LED TECHNOLOGY - They require less maintenance, consume less power and produce 300% more light on the road. Using a total of 27 powerful LEDs per light, nothing is brighter! With 9 DRL LEDs, 10 low beam LEDs, and 8 high beam LEDs there is no place too dark.
- PLUG N' PLAY - Drop in replacement for most vehicles with standard 4 x 6 headlights and 2A1 headlights commonly found in Semi-Trucks and Fire Fighter apparatuses. They are plug and play replacements for the low beam lights in four headlight systems. The light is equipped with an OEM H4 connector that comes standard on many different vehicles. With an optional DRL to be wired in separately. No splicing, no cutting. Just drop it in, and go for a drive.
- LOTS OF POWER, LOTS OF LIGHT - At over 2000 lumens per unit there is no trail too dark. Featuring the latest in LED projector technology the SL4627B will light up everything in your path. Utilizing Bullseye lenses, the low beam is lightly diffused to increase the field of vision and create a wide beam pattern. While the high beam uses clear lenses that provide the farthest throwing light possible.
