OEM Blinker Relay 3.201.400

A blinker relay, also known as a turn signal relay, is an essential component in a vehicle's electrical system responsible for controlling the blinking of the turn signals and hazard lights. When the driver activates the turn signal lever, the relay receives the signal and initiates the blinking action by alternately making and breaking the electrical circuit. This causes the turn signal lights to flash on and off, providing a visual indication to other drivers of the vehicle's intention to turn or change lanes.

In addition to facilitating the blinking function, the blinker relay ensures that the turn signals operate at a consistent rate, regardless of the load on the circuit. This means that even if one or more bulbs burn out or are replaced, the remaining lights will still blink at the correct speed. A malfunctioning blinker relay can lead to issues such as rapid blinking or failure of the turn signals to operate altogether, making its proper functioning crucial for safe driving and effective communication on the road.
