Headlight assembly (Part 90020664), used as a primary forward lighting unit on terminal tractors and yard trucks. It’ the sealed high intensity lamp that provides high and low beam illumination for the vehicle’s front lighting system. When the operator switches on the headlights, this sealed assembly delivers both low and high beam light output, enabling safe operation in dark or low visibility environments essential for night yard operations or when maneuvering trailers in poorly lit areas.
