The 2015-2018 S550 Mustang is one of the best pony cars ever built — a daily driver that doubles as a track weapon or show car on weekends. But there's a ton of room for improvement over Ford's stock lighting. Here are the top 5 lighting modifications for the S550 Ford Mustang.

Multicolor DRL LED Boards
The Multicolor DRL LED Boards are a direct replacement for the factory LED circuit boards inside the 2015-2017 Mustang's headlights. These boards feature true RGBW functionality — not just RGB — so you get a pure, OEM-style white DRL on the road and full multicolor capability when parked. Pair them with the Bluetooth RGBW Controller for thousands of color combinations from your phone.
Available in RGBWA with an added amber chip that enables the boards to function as a secondary front turn signal — your white DRL converts to a bright amber sequential flasher when you signal.
Tail Light Sequencer
Ford's sequential turn signal is a signature Mustang feature — the Tail Light Sequencer extends that pattern to braking, locking/unlocking, and hazards. 100% plug-and-play with no splicing required. Installs in under 10 minutes. Fits 2010-2018 Mustang models.
LED Sidemarkers
Despite using LEDs elsewhere, the 2015-2018 Mustang still relies on an outdated incandescent sidemarker bulb. The LED Sidemarker Kit delivers a brilliant strip of LED light in an OEM-quality housing — installs in 5 minutes with no tools required. Available with smoked or clear lenses for a custom look.
Sequential LED Turn Signals
Sequential LED Turn Signals for the 2015-2017 Mustang are a full housing replacement for the factory turn signal. CAD-designed housings with OEM-quality durability, three distinct signaling patterns, and an optional Daytime Running Light Harness that provides a crisp white DRL that converts to bright amber when signaling. One of the most popular S550 mods available.
Interior LED Bulbs
Upgrading the 2015-2018 Mustang's interior lighting has a huge impact on the everyday look and feel. LED replacement bulbs are available for the map light, trunk light, glove box light, and vanity mirror light. Multiple colors and brightness levels available — cool white, pure white, natural white, red, blue, and amber. 100% plug-and-play with no modification needed.
