2024–2026 Ford Mustang S650 RGB Bluetooth Side Markers w/ Rear Diffuser Reflectors – 6PC Kit

Full RGB | Bluetooth App Control | Plug & Play | Front + Rear Synchronized Lighting | HappyLighting Compatible

Your Mustang shouldn't disappear when the sun goes down.

Introducing the Auto Addict USA 6-Piece RGB Bluetooth Side Marker & Rear Diffuser Reflector Kit for the 2024–2026 Ford Mustang S650—designed for Mustang owners who love lighting up their build, creating custom accent colors, and making their car stand out whether it's parked at a show, cruising at night, or pulling into the next meet.

This isn't just another set of replacement reflectors.

It's a fully synchronized RGB accent lighting system designed specifically for the S650 Mustang platform—and best of all, it's a FULL PLUG-AND-PLAY APPLICATION.

No wiring directly to the battery. No complicated custom wiring. No separate controller mounted in your engine bay.

Plug it in, connect through Bluetooth, open the HappyLighting App, and bring your Mustang to life.

🌈 6-Piece RGB Lighting Package

The complete Auto Addict USA kit includes RGB lighting for the front, rear, and diffuser area of your S650 Mustang.

Complete 6PC Kit Includes:

• 2 Front RGB Side Markers
• 2 Rear RGB Side Markers
• 2 Rear Diffuser RGB Reflectors
• 2 Bluetooth Control Boxes
• Plug-and-play connections required for installation

The result is a complete lighting package that carries your accent color from the front fenders all the way through the rear diffuser.

One Mustang. One theme. One synchronized look.

⚡ 100% Plug & Play — NO Battery Wiring

This is one of the biggest advantages of the Auto Addict USA system.

The kit has been engineered as a full plug-and-play application, eliminating the need to run additional wiring directly to your vehicle's battery.

Simply connect the supplied components into their designated connections and you're ready to pair the system through Bluetooth.

No complicated installation.

No direct battery wiring.

No cutting into your Mustang just to enjoy RGB lighting.

We wanted the system to feel like it belonged on the S650 from the beginning.

📲 Powered by the HappyLighting App

Already running Auto Addict USA RGB headlights or taillights?

It gets even better.

The Side Marker & Rear Diffuser Reflector Kit operates through the same HappyLighting App used with our compatible RGB headlight and taillight systems.

From your smartphone, you can control your accent lighting and personalize the appearance of your Mustang directly through the app.

Create a clean single-color theme for a show.

Switch up the look for a nighttime cruise.

Match your lighting to the personality of your build.

The control is right in your pocket.

🔗 Dual Bluetooth Control – Fully Synchronized

To create a complete front-to-rear lighting experience, the kit utilizes two Bluetooth control boxes.

Bluetooth Box #1 – Front

The first Bluetooth controller connects to the:

Front Left + Front Right RGB Side Markers

Bluetooth Box #2 – Rear

The second Bluetooth controller connects to the:

Rear Left + Rear Right RGB Side Markers

and

Rear Left + Rear Right Diffuser Reflectors

Once connected through HappyLighting, the system can be synchronized to create a unified lighting theme across the Mustang.

That means your front side markers, rear side markers, and rear diffuser lighting can all work together instead of looking like separate aftermarket lighting upgrades.

🔥 Built for the Mustang Crowd

The S650 Mustang community loves customization.

Wheels. Carbon fiber. Aero. Exhaust. Suspension. Lighting.

The Auto Addict USA RGB 6PC Kit was developed for owners who want that one extra detail that completely changes the personality of the car after dark.

✨ One App. One Mustang. Full RGB Presence.

Headlights → Front Side Markers → Rear Side Markers → Rear Diffuser Reflectors → Taillights
