Features Compatible with Ford Mustang 2015-2023 Converts reverse light to also function as a running light and 4th brake light OEM connectors and wiring harness for simple plug-and-play installation Assembled in USA 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.

Don’t buy for restaurant industry
Size: 10.5, Color: Black, Size: 10.5, Color: Black
Good looking shoes, fairly comfortable and good value based on the description shared, so I don’t feel it’s fair to rate them lower than 4 stars. I had high hopes for them based on previous reviews from others saying they wore them in the food and beverage industry that mentioned their quality and durability, however I strongly recommend looking elsewhere if you do. I purchased these to wear working in a full service upscale restaurant and in less than two months have managed to have torn the material on the middle exterior section and the bottoms of the shoes are already completely worn down. Good design, but the durability needs to be improved if they’re to hold up for that industry.

DO NOT BUY (lasted less than 7 months)
Size: 11, Color: Black, Size: 11, Color: Black
I bought these for work as a bartender in August of 2025. By December, the tops were scuffed, frayed, and peeling beyond repair, and by February, the soles were coming off. I’ve never had a pair of shoes with such low quality.

Most comfortable shoes, right out of the box!
Size: 8.5, Color: Cognac Napa Leather
Oh my! So, my ordering of shoes online has been hit or miss - 1/2 size too big or too small; too wide or not wide enough. Enter these Marc Joseph shoes… such a game changer. They fit like a glove, exceptionally comfortable, and easy to slip in and out of. I like them so much that I am shopping for another pair. So far, the size, quality, fit, feel, look, and comfort make this pair my dedicated first pick. Btw, I have been wearing them for six hours and they are still very comfortable! I highly recommend these shoes.
