Stock Sucks: No doubt the S550 Mustang is a capable car, and if you've already upped the ante by making more power, new wheels, and fatter tires, then it's time to ditch the stock lighting setup too. Morimoto's unbeatable XB LED fog lights have been top sellers in our catalog forever, and we couldn't be more excited to see the lineup expand with offerings such as the new high-performance XB Mustang LED tail lights too! Compatible: With all S550 Mustangs from 2015-2020, these complete tail light assemblies will swap directly in place of the original Mustang tail lights, use all of the stock mounting points, and should only take around 30 minutes to install. Plug n Play: Wiring is easy too! The Morimoto XB LED tail lights are designed to work without any special wiring. They will plug into the factory connectors for the 2015-2018 Mustang's stock tail lights and each assembly includes all necessary connectors, rubber seals, and pigtails for a plug n play install. No additional resistors, modules, etc needed! Style: Inspired by the new Ford GT, while they look radical, the Morimoto XB tail lights don't look out of place like other aftermarket options. The piano black finish matches the OEM trunk trim perfectly. The geometry flows with the body lines like a boss. The XB LED tails for your 'Stang are available with either a smoked or red lens. Both will illuminate red. Well-Built: Their durable polycarbonate lens will resist the test of time, keeping the housings looking new for many years to come. The injection molded ABS housing is light-weight and much stronger than comparable cheap alternatives. The Morimoto XB LED Tail Lights may not be the cheapest new tail lights for your Mustang, but they're OE quality, and as the saying goes, you pay for what you get. Although the tails are new, we've sold many thousands of the XB Fog lights and to date, have only seen a small handful with problems... no joke
