Truck-Lite 44217Y – Super 44, 4" Round Yellow In-Phase LED Rear Turn Strobe Light (6 Diode, Turn Signal Override, Class II, Hardwired, Packard Connector 282087 / Weather Connector 12015791, 12V)
Combine rear hazard warning and turn signal functionality with the Truck-Lite 44217Y Super 44 In-Phase LED Strobe Light. Designed for heavy-duty commercial trucks, emergency fleets, tow vehicles, and utility trailers, this 4-inch round yellow lamp features 6 high-intensity LEDs with integrated Turn Signal Override technology. Built for slim-profile grommet mounting, fully encapsulated against moisture and corrosion, and pre-wired with a Packard/Weather 4-wire connector system, the 44217Y provides dual-function warning safety with solid-state LED reliability.
The Truck-Lite 44217Y Super 44 In-Phase Rear Turn Strobe Lamp delivers high-visibility safety by combining an intense quad-flash warning strobe with vehicle turn signal signaling. Designed around Truck-Lite's signature 6-diode optics pattern, this lamp aesthetically matches standard Stop/Tail/Turn and Back-Up light setups across commercial fleets. Its built-in turn signal override feature automatically pauses the strobe pattern when the turn signal is activated, ensuring turn indications are clearly visible to surrounding traffic.
Engineered as an In-Phase unit, the 44217Y allows seamless multi-lamp synchronization across your vehicle setup. Pairing two in-phase lamps produces a simultaneous quad flash, while pairing an in-phase lamp (44217Y) with an out-phase lamp (44218Y) creates a lateral alternating strobe pattern—all without needing an expensive external flasher module or control box. This built-in lateral circuitry reduces installation time, slashes wiring complexity, and cuts hardware costs.
Crafted with an ultra-slim profile depth (less than 1 inch), the 44217Y fits effortlessly into tight mounting locations using standard 4-inch round grommets. The electronics are completely encapsulated inside an ABS housing with an acrylic lens, offering maximum protection against road moisture, chemical exposure, and high vibration. Hardwired with a 4-wire pigtail and an integrated Packard 282087 / Weather 12015791 connector, the 44217Y ensures quick, weather-sealed plug-and-play connection into 12V electrical harnesses.
