Sequential LED taillights that ditch the factory four-circle look for a clean Ferrari-style bar — with proper sweeping turn signals. Pick your lens: red, clear, or smoked.
Sequential LED · 3 Lens Options · Plug-and-Play

These swap the S550’s factory taillights for a full-LED Ferrari-style design — a cleaner horizontal light signature with sequential turn signals that sweep instead of blink.
Plug-and-play into the factory harness, no splicing. Choose the lens that matches your build: red for OE-plus, clear for a fresh look, or smoke for blacked-out.
Turn signals sweep across the lens instead of flashing — the modern animated look, built in.
Bright, even LED illumination across brake, tail, and reverse — no dim incandescent bulbs.
Red Lens (OE-plus), Clear Lens (fresh), or Smoke Tinted (blacked-out). Pick from the dropdown.
Connects to the factory taillight harness — no cutting, no splicing, no resistors in most cases.
Cleaner horizontal light bar look that modernizes the S550 rear end.
Weather-sealed units built to handle daily weather and washing.
