KanSmart LED Sequential Mirror Turn Signals for BMW 1/2/3/4 Series — Smoked Waterproof LEDs, Plug-and-Play

KanSmart LED Dynamic Sequential Turn Signals are plug-and-play mirror indicators designed to replace original BMW mirror signals with smoked, waterproof, super-bright sequential LEDs for clearer, modern signaling.

Upgrade your BMW’s mirror indicators with a modern, attention-grabbing sequential turn signal that fits many 1, 2, 3 and 4 Series models (plus select X1 and i3 years).
