Truck-Lite 4050 – Signal-Stat 4" Round Red LED Stop/Turn/Tail Light, 24-Diode, PL-3 Connection

Upgrade your vehicle’s lighting with the Truck-Lite 4050 Signal-Stat LED Stop/Turn/Tail Light. This high-performance 4-inch round lamp is a favorite for heavy-duty trucks and trailers, offering a modern, energy-efficient alternative to traditional incandescent lighting. Featuring a unique 24-diode LED array, this light produces a full-pattern light output that ensures maximum visibility for stop, turn, and tail signaling.

The Signal-Stat 4050 is built for extreme durability. Its epoxy-encapsulated electronics are fully sealed to protect against moisture, road salt, and corrosion, which are the leading causes of lighting failure. Because LEDs are solid-state and have no fragile filaments, this unit is exceptionally resistant to the shock and vibration found in rigorous commercial and vocational environments.

Designed for easy installation, the 4050 uses a standard PL-3 right-angle connection and fits into standard 4-inch grommet mounts. With its low current draw, it reduces the load on your vehicle’s electrical system, helping to extend battery and alternator life while providing long-lasting, DOT-compliant safety.
