Truck-Lite 4051A Signal-Stat LED Clear/Yellow 4" Round Front/Park/Turn Signal Light (12V, 24-Diode, Custom Clear Lens, PL-3 Connection, Sealed Polycarbonate Lamp)
Bring a sleek, modern look to your commercial rig while maximizing forward safety with the Truck-Lite 4051A Signal-Stat LED Front/Park/Turn Signal Light. A highly popular choice for owner-operator show trucks, custom fleets, and premium trailers, this 4-inch round light pairs a crisp, clear polycarbonate lens with a high-intensity yellow (amber) 24-diode LED array. When unlit, it offers a clean, custom clear-lens aesthetic; when activated, it instantly displays a bright, full-pattern amber output for dual-function parking and turn signaling.
Engineered to survive the harshest environments on the highway, the Truck-Lite 4051A features fully enclosed, epoxy-encapsulated electronics that isolate the circuit board from heavy road vibration, moisture, and chemical corrosion. Because solid-state LEDs have no delicate filaments to fracture, this light eliminates the premature burnouts common in traditional incandescent bulbs. This energy-efficient 12V DC lamp draws minimal current, flush-mounts into standard 4.5-inch panel cutouts, and connects via standard right-angle 3-prong PL-3 pigtails.
