A DRL relay, or Daytime Running Light relay, is an electrical component used in vehicles to control the operation of daytime running lights. These lights are designed to enhance visibility during daylight hours, increasing safety on the road. The relay activates the DRL circuit when the vehicle is in operation, allowing the lights to turn on automatically without requiring the driver to manually switch them on. If the relay fails, it can result in the daytime running lights not functioning properly.
The daytime light relay is typically located in the vehicle's fuse box, which can be found under the dashboard, in the engine compartment, or sometimes in the trunk, depending on the make and model of the vehicle. It is responsible for controlling the operation of the daytime running lights. To locate it, refer to the vehicle’s owner's manual for specific diagrams and relay identification.
