Overview
Custom Appearance. If you're looking for a way to make your S550 Mustang stand out, here's a perfect solution! The Diode Dynamics 4th Brake Light Kit converts your factory reverse light to shine both bright white, and red. Not only do you get an upgraded backup light, you can also add a red running and brake light, for a unique, modern look on the road.
Red Running Light: The red light comes on at 50% brightness anytime you have your parking lights or headlights on, to serve as a rear fog lamp. This provides a distinct appearance at night, complementing the factory LED tail lights.
4th Brake Light: When you hit the brakes, the red light powers at full brightness, to serve as a supplementary brake light, for greater visibility and a unique look.
White Reverse Light: Anytime you're in reverse, the red shuts off completely, so your backup light can illuminate in a crisp, white color. There is no change to the factory reverse function, you just get an improved output from the white LED!
Easy Installation. Using OEM connectors and the included wiring harness, this kit is 100% plug-and-play and installs in minutes. Actual installation time is less than 20 minutes. This is one of the easiest ways to make your Mustang stand out on the road!
Reliable Operation. This module has been designed with quality components, custom-tooled OEM-grade connectors, and includes embedded circuit protection, for high reliability over time. It is proudly assembled in St. Louis, Missouri by Diode Dynamics Manufacturing.
