-
World’s First Single-Diode S/T/T Lamp: Precision optics diffuse a single high-output LED diode to mimic traditional incandescent appearances while outputting superior light spread.
-
Faster Driver Reaction Time: Instant illumination gives trailing motorists crucial additional stopping distance to help prevent rear-end collisions.
-
Low Current Draw: Operates on significantly lower amperage (Major 0.47A / Minor 0.03A) to extend battery and alternator life, leaving more power available for other vehicle systems.
-
Corrosion-Proof Fit 'N Forget S.S. Plug: Engineered with Truck-Lite's Fit 'N Forget Super Seal connector to isolate terminal pins from moisture, salt, and dirt intrusion.
-
Sealed Polycarbonate Construction: Sonic-welded polycarbonate lens and housing assembly create an airtight, weatherproof barrier against the elements.
-
Standard Grommet Fitment: Standard 2" x 6" oval profile designed for easy, vibration-dampening grommet mounting in standard trailer cutouts.
-

Truck-Lite 66250R – Super 66 Red Oval 1-Diode LED Stop/Turn/Tail Lamp (Fit 'N Forget S.S., Grommet Mount, 12V)
Revolutionary Single-Diode Efficiency with the Truck-Lite 66250R Super 66 LED Light
Upgrade your heavy-duty truck, commercial trailer, or service body with the Truck-Lite 66250R Super 66 Red Oval Single-Diode LED Stop/Turn/Tail Lamp. Celebrated as the world's first single-diode LED S/T/T lamp, the Super 66 series combines the smooth, traditional look of a classic incandescent fixture with the high optical clarity, energy efficiency, and extended service life of advanced solid-state LED technology.
Designed to enhance road safety, instant-on LED performance alerts trailing drivers faster than traditional incandescent bulbs—yielding an average 3-foot reaction time advantage for every 10 mph. Its fully sealed, epoxy-encapsulated polycarbonate housing locks out moisture, salt spray, and road debris while protecting internal components against severe shock and heavy road vibration. The lamp features Truck-Lite's corrosion-resistant Fit 'N Forget Super Seal connection system for reliable electrical contact.
