Truck-Lite 44231Y – Super 44, 4" Round Yellow LED Rear Turn Signal Light (42 Diode, White Polycarbonate Flange Mount, Fit 'N Forget S.S., 12V)
Maximize signaling clarity and roadway safety with the Truck-Lite 44231Y Super 44 LED Rear Turn Signal Light. Built for commercial trucks, step vans, motorhomes, service fleets, and heavy equipment, this 4-inch round yellow light features a high-intensity 42-diode LED array that illuminates faster than traditional incandescent bulbs—providing trailing drivers up to an extra 3 feet of stopping distance for every 10 mph. Complete with an integrated white polycarbonate flange for clean, bright surface mounting, low power draw, and Truck-Lite's corrosion-resistant Fit 'N Forget® S.S. connection system, the 44231Y delivers heavy-duty rear turn signaling performance.
When reaction time matters most on the highway or job site, the Truck-Lite 44231Y Super 44 Yellow LED Rear Turn Light provides instant-on visual indication. Powered by 42 high-output amber/yellow LEDs, this solid-state turn signal lamp illuminates instantly when engaged. This fraction-of-a-second reaction advantage gives trailing drivers earlier awareness and additional stopping distance, significantly reducing the likelihood of rear-end accidents during sudden stops or lane changes.
Featuring a permanently attached white polycarbonate flange, the 44231Y mounts directly and securely flush onto vehicle bodies, step van panels, and white trailer walls—providing a clean, matching aesthetic without requiring separate rubber mounting grommets or mounting brackets. Operating on a standard 12V DC system, its advanced LED engineering consumes significantly less amperage (0.42A Minor / 0.65A Major) than traditional incandescent lights, preserving battery life and reducing overall load on your alternator.
Built without fragile filaments that burn out or break from road impact and engine vibration, the Truck-Lite 44231Y is engineered for long-haul commercial durability. The fully epoxy-sealed polycarbonate lens and housing shield internal components against moisture, road salt, dirt, and chemical exposure. Equipped with Truck-Lite’s signature Fit 'N Forget® Stainless Steel (S.S.) connector, this light prevents terminal oxidation and moisture corrosion, ensuring long-term service life backed by a Limited Lifetime Warranty.
