The full breakdown.
Overview
Add custom Steeda styling to your S550. Whether or not you chose the factory illuminated “Mustang” door sills as an option when purchasing your 2015+ Mustang GT, GT350, EcoBoost or V6, these “Steeda” illuminated door sills will work with your Mustang. These custom door sills will go perfectly with your Steeda-equipped Mustang and let people know your brand of choice!
Our Steeda S550 Mustang Illuminated Door Sill Plates light up with the “Steeda” logo and function just like the factory illuminated door sills turning on and off when the door opens and closes. If you have Ford’s MyColor System option on your S550, our Steeda door sills have the benefit of working in unison with the system allowing you to customize the color light your illuminated doors sills give off. If you chose not to go with the MyColor System you can still use the provided wiring to make your door sills illuminate white, red, blue or green. If you did not have factory illuminated door sills this kit will still work in your S550 and you have the same option to choose from white, red, blue or green light.
These Steeda illuminated door sills are made in the USA using OE quality materials. Our kit comes complete with driver and passenger side doors sills, and all necessary hardware for installation. They will work on any GT, GT350, EcoBoost or V6 Mustang with or without factory illuminated doors sills. The kit includes step by step instructions for wiring up these door sills to your Mustang without factory illuminated door sills.

— Why we stock Steeda
OE-style engineering, in-house manufacturing, race-proven on Steeda's own SCCA program.
Steeda has been engineering Mustang — and now Explorer, Focus, F-150, and Maverick — parts in Valdosta, Georgia since 1988. CNC-machined billet, proprietary CAD-driven suspension geometry, and a factory SCCA Majors road-racing team that runs their own parts on the track every weekend. When you bolt a Steeda part onto your car, it's the same part Steeda's own race cars run.
We carry Steeda because the fitment is right the first time, the warranty is real (lifetime on Steeda-manufactured parts), and the install instructions don't leave you guessing. Drop the car at our Thousand Oaks shop and our techs handle the fit-up — or order with confidence and run it yourself.
