Overview
Ensure your trailer is seen from a mile away with this premium aftermarket Red 4 Inch LED Light distributed by FleetPro Parts & Tires. Dim, flickering, or burnt-out incandescent tail lights are a leading cause of rear-end collisions and guaranteed DOT inspection failures. Manufactured by Automann to strict Fleet Standard specifications, this high-performance Stop/Turn/Tail (S/T/T) light utilizes advanced LED technology to provide instant-on response times and superior brightness compared to traditional bulbs. We stock these heavily right here in our Hanover Park, Illinois warehouse to ensure lightning-fast shipping for fleets, trailer repair shops, and owner-operators nationwide.
High-Lumen Visibility: The Red 4 Inch LED Light Advantage
This Red 4 Inch LED Light is engineered to survive the brutal vibrations and weather exposure of commercial over-the-road hauling. It features 10 high-output diodes protected by a rugged, sonic-welded polycarbonate lens that creates a permanent, moisture-proof seal. The integrated PL-3 male connector on the back makes for a fast "plug-and-play" installation into existing wiring harnesses. Designed for standard 4-inch round grommet mounting, this 12V light is the perfect upgrade for any rig needing dependable, long-lasting rear illumination.
At FleetPro Parts & Tires, we know that compliance is king. This Automann LED light meets all DOT, SAE (Code: STI2I6), and FMVSS requirements, ensuring your truck or trailer remains 100% road-legal. It acts as a direct, high-efficiency replacement for highly searched industry numbers like Truck-Lite 44302R, Optronics STL43RB, and Peterson 417R-3. Switch to LED today and stop worrying about blown bulbs on the highway.
