Q:WHAT DOES THIS PART DO
A:Hi YUKI, glad to assist you! The DRL (Daytime Running Light) system turns the headlights on while the engine is running in the daytime. This means that the headlight bulbs are turned on at all times, which shortens bulb life. To prevent this, the system’s circuitry reduces the light intensity of the headlights while DRL is on. This is accomplished mainly by one of the following main three types of circuitry. (1)Type in which light intensity is reduced by DRL resistor. Light intensity is reduced via the DRL resistor while the DRL system is operating. (2)Type in which light intensity is reduced through series connection of headlights. Light intensity is reduced by having current flow in series of the left-hand and right-hand headlights while the DRL system is operating. (3)Type in which light intensity is reduced by duty control in DRL main relay. Light intensity is reduced by a duty control circuit in the DRL main relay while the DRL system is operating.
Q:do you have some part that make the headlamp light go off during the day?
