Turn signal lamps, also known as indicator lights or blinkers, are essential for communicating a vehicle's intended direction to other road users. Located at the front, rear, and sometimes on the sides of a vehicle, these lamps flash when the driver activates the turn signal lever, indicating an upcoming turn or lane change. They provide a clear, bright signal that enhances safety by reducing the risk of accidents during maneuvers. Available in various designs, including traditional incandescent bulbs and modern LED versions, turn signal lamps also contribute to the vehicle's overall design, offering both functionality and style.
