Turn signal

A turn signal, also called an indicator, is a flashing signal light that forms part of a vehicle’s lighting system. It informs other road users of an intended change of direction, such as turning or changing lanes.

In Europe, turn signals emit amber light. In other markets, particularly North America, red rear turn signals are also permitted under certain conditions.

Turn signals may be installed as separate units or integrated into other lighting assemblies, such as a rear light.
