For 11-21 Peterbilt 579 587 Sequential LED Turn Signal DRL Headlight Lamps Black

A headlight (headlamp) is a lamp attached to the front of a vehicle to light the road ahead. Headlight performance has steadily improved throughout the automobile age, spurred by the great disparity between daytime and nighttime traffic fatalities. Headlights are one of the most important components of your vehicle; they allow you to see the road in front of you clearly during the night and in any bad weather that may arise. Our headlights upgrade the face of your vehicle with clear style and extreme range.
