Truck-Lite 44218Y – Super 44, 4" Round Yellow Out-Phase LED Rear Turn Strobe Light (6 Diode, Turn Signal Override, Class II, Hardwired, Packard Connector 282087 / Weather Connector 12015791, 12V)
Enhance rear warning visibility and turn safety with the Truck-Lite 44218Y Super 44 Out-Phase LED Strobe Light. Designed for heavy-duty commercial trucks, emergency vehicles, utility trailers, and service fleets, this 4-inch round yellow lamp features 6 high-output LEDs with integrated Turn Signal Override technology. Engineered specifically as an Out-Phase unit to enable lateral alternating flash configurations, this ultra-slim, fully encapsulated lamp pairs with an In-Phase companion (such as the 44217Y) to deliver synchronized warning performance without needing expensive external flashers.
The Truck-Lite 44218Y Super 44 Out-Phase Rear Turn Strobe Lamp provides essential safety and high-conspicuity hazard warning while preserving full turn signal capability. Utilizing Truck-Lite's signature 6-diode optic layout, it offers a uniform, professional appearance that matches standard Stop/Tail/Turn and Back-Up lamps on commercial vehicle bodies. When connected in tandem with an In-Phase lamp (Truck-Lite 44217Y), the Out-Phase 44218Y produces a lateral alternating quad-flash pattern, cutting through visual clutter without requiring bulky external control boxes or flasher modules.
Vehicle safety is paramount when working near active traffic. The 44218Y is equipped with an internal turn signal override function that automatically pauses the quad-flash warning strobe when turn signals are engaged, ensuring turn indications are clearly visible to trailing motorists. Once the turn signal cancels, the lamp seamlessly resumes its strobe warning pattern.
With a slim profile depth of under 1 inch, the 44218Y easily fits tight rear-panel installations using standard 4-inch round grommets. The solid-state LEDs and internal electronics are fully potted inside an impact-resistant ABS housing with an acrylic lens, protecting against water immersion, salt spray, road debris, and severe vibration. Hardwired with a 4-wire lead terminating in a Packard 282087 / Weather 12015791 connector, this strobe light ensures weather-sealed, plug-and-play installation into 12V electrical systems.
