Stop Turn Tail LED Light - 4 Inch Round Red 24-Diode with Reflector - Grand General 78273BP 571.LD40R24

Stop chasing burnt-out bulbs on the back of the trailer with this 4in round red stop, tail and turn LED lamp distributed by FleetPro Parts & Tires. It packs 24 high-output diodes behind a red lens with a built-in reflector, so the rear of the unit is conspicuous whether the lamp is lit or the trailer is sitting dark in a drop yard. Dim, flickering or dead rear lighting is a leading contributor to rear-end collisions and a guaranteed out-of-service item at the scale. 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.

Brighter Brake Light, Faster: The 24-Diode Red LED Advantage

Twenty-four diodes across a 4in face put out a strong, even signal instead of the uneven glow you get from a low-count lamp, and the LED lights the instant the brake switch closes. That fraction of a second of earlier warning is real distance to the car behind you at highway speed - which is the whole argument for taking the rear of the trailer to LED. The lamp runs on 12 Volt, carries SAE code STI for stop, tail and turn service, meets FMVSS 108 and is DOT compliant.

It is a grommet mount lamp that drops straight into the standard grommets and flanges already in the rear panel, and it weighs 0.45 lbs. Where a fleet is still on incandescent in this position, Automann's matching bulb-type lamp is 571.LG40R. This unit is a direct replacement for highly searched industry numbers including Grand General 78273BP, UBLights MTLED4000-24R and MTLED400024R, and Uni-Bond LED4000-24R.
