A headlight relay is an electrical component in a vehicle that controls the flow of power to the headlights. It acts as a switch that allows a low-current circuit (like the headlight switch inside the cabin) to safely control a high-current circuit that powers the headlights. This protects the wiring and switch from overheating and ensures reliable headlight operation.
