About Headlight Relay

The headlight relay alludes to the electrical parts that disrupt the flow between conductors via an electromagnet that controls and activates the headlights. It also is responsible for brightness and deactivation.

Headlight relay importance

The headlight relay in the car is important to the formation and functionality of the headlights. So when you turn on your headlights, that switch triggers a relay. When the relay is triggered, it provides the electrical connection between the headlight bulbs and the battery. Fuses are also required to supply a sacrificial failure point to protect the wiring.

Common issues with a faulty headlight relay

A faulty headlight relay can lead to the headlight doors not giving way or they may be stuck open.
