Grand General's Fleet LED (light emitting diodes) lights offer an inexpensive way to upgrade your vehicle lighting. LEDs are brighter and have lower amperage draw making it possible to add more lighting without upgrading your charging system. Oval lights are a commonly used size in heavy and medium duty trucks. This amber oval Fleet LED is used for park/turn/clearance functions and uses a standard 3-prong pigtail. The Fleet series is DOT (Department of Transportation) compliant for street legal lighting and is an excellent value choice.
