Full LED replacement tail light assemblies with sequential turn signals, an LED reverse light, and a running light that switches between red and amber.
why this one — The back of a 2017-2022 Super Duty is where it looks most dated next to a new one, and this is the cheapest single change that fixes both the look and how fast your brake lights come on behind you. Against the older-body LUXX kit this one costs more because it is the newer tooling. Read the fitment line twice before ordering: this specific part number is for trucks without the blind spot sensor, and it replaces halogen assemblies.
A power claim does not apply to a taillight.
This version is for trucks WITHOUT the factory blind spot sensor (BLIS), and it replaces halogen tail lights, not factory LED ones.
