We’ve already tempted and teased our readers with a behind-the-scenes tour of the Unique Performance Shelby continuation cars—the GT 350SR and the GT 500E (Ford Builder, Mar. ’05, page 67). Many of you probably lust after one or both of these cars, but not all of us can afford to purchase one yet. And because of their limited numbers, their prices do, unfortunately, put them out of reach of many of us Ford enthusiasts. That’s the bad news. But there is good news; don’t assume that because you cannot buy a genuine continuation Shelby, you can’t build a car that drives just like one. Unique Performance sells not only the cars as complete packages, but they understand the situation quite clearly and have made available many of the individual parts and assemblies used to build their cars.

Each Aurora setup comes as a complete, ready-to-install system. Inside the box, you’ll find two precision-engineered LED taillight units, a solid-state LED flasher relay designed for smooth, consistent sequencing, and a pair of low-profile chrome bezels with hidden hardware—a subtle but brilliant design move that eliminates visible screws for a cleaner, more refined finish.
These bezels strike the perfect balance between factory-correct styling and modern refinement, maintaining that unmistakable Mustang rear profile while sharpening it just enough to catch the eye. When those sequential turn signals sweep across the lenses, the effect is pure automotive theater—subtle, sophisticated, and unmistakably modern.
Prefer to keep your Mustang’s exterior completely original? Pyramid thought of that, too. The Aurora housings are fully compatible with your stock bezels and lenses, allowing you to retain a 100% factory appearance while enjoying the benefits of today’s lighting technology hidden beneath the surface.




Key Features:
- Direct retrofit for 1964½–1966 Mustangs—no permanent mods
- Ultra-bright, even LED output with sequential signal pattern
- Hidden hardware, low-profile bezels for a clean factory aesthetic
- Includes reproduction lenses and a solid-state flasher relay
Installation couldn’t be easier—it’s a true plug-and-play retrofit that requires no cutting, no drilling, and no irreversible modifications. Everything bolts right into the factory mounting points, transforming your taillights in an afternoon. The result is a factory look that glows with confidence and clarity far beyond what Ford ever offered in the mid-’60s.
Classic looks. Modern lighting. Zero compromise.
👉 Bring your Mustang into the modern era—upgrade to the Sequential Aurora Taillights today!
