Dynamic/Sweeping (Audi Style) Turn Signal

Sequential indicators, often called dynamic turn signals, are turn lights on a car that illuminate in a progressive pattern rather than all at once. Instead of flashing together, the lights "flow" in the direction of the turn signal, usually starting from the inside edge and moving outward.

How They Function

When activated, the LED lights within the indicator light up in a timed sequence, creating a "wave" effect that is visually striking. This sweeping light motion usually completes in under a second but is highly noticeable.

Key Advantages

1. Better Visibility: The moving light pattern grabs attention more effectively, enhancing safety.
2. Stylish Look: Sequential indicators give a modern, high-tech look that’s popular on cars from brands like Audi and Lexus.
3. Clear Directionality: The flowing light clearly shows the direction of the turn, making it easier for others to anticipate the car’s movement.

Sequential indicators started in high-end cars but are becoming more common in regular models as the technology becomes widely adopted.
