A fog lamp relay serves as an electrical switch that controls the power supply to fog lamps in a vehicle. It allows the fog lamps to operate without drawing excessive current through the vehicle's main wiring, thus protecting the electrical system. By using a relay, the fog lamps can be activated with a lower-current switch, improving safety and reliability. Additionally, it helps ensure that the fog lamps only operate when needed, enhancing visibility in adverse weather conditions.
