TURN SIGNAL INDICATOR. A turn signal indicator is a component of a vehicle’s lighting and signaling system designed to inform other road users about the driver’s intention to perform a maneuver such as turning, lane changing or making a U‑turn. This component is an essential part of the vehicle safety system and provides visual signaling through a blinking light. Turn signal indicators are typically installed at the front and rear of the vehicle, as well as on side mirrors or fenders, ensuring clear visibility for other drivers and pedestrians. The operation of the turn signal is controlled by the turn signal switch and supported by a relay or electronic control unit that provides the intermittent flashing mode of the light source. The construction of a turn signal indicator may include a housing, reflector, lens and a light source such as a halogen bulb or LED module. Modern turn signal indicators are often based on LED technology, which offers improved brightness, longer service life and better energy efficiency. Reliable operation of turn signals is essential for safe driving and compliance with traffic regulations. The catalog includes turn signal indicators of various types and designs intended for installation on different passenger cars, SUVs and commercial vehicles.
