DRL Controller, Fydun Car Led Daytime Running Light Controller Automatic ON/OFF Switch Relay Harness Dimmer Module for 12V

Intelligent controller design: With constant light, dimming, delay and automatic switching functions. When the battery is connected, the daytime running lights will light up for about 15 seconds and then go out. This is normal (implements the delay function). Then you have to start the car. When the voltage reaches 13 V +, it will start working. Waterproof: The waterproof design is practical and has a long service life. High-quality ABS material makes it strong, corrosion-resistant and durable. Easy installation: 1. Connect the positive and negative poles of the daytime running lights on the left and right sides first, and then connect the negative poles first. 2. Connect the input red and black wires to the fuse on the controller to light up the positive and negative poles of the battery, and the output red and black terminals light up the positive and negative poles of the daytime running lights. Smart start: When the car starts (the voltage must be higher than 13 V +), the driving lights will automatically turn on during the day. When the headlights (or reading lights) are turned on, the daytime running lights are dimmed; when the car is turned off (the voltage must be lower than 12.5 V), the daytime running lights go out after 15 seconds. Easy to carry and store: The compact and portable design of our DRL controller makes it easy to carry around and store wherever you please. With no need to change electrical lines, installation is hassle-free and convenient for anyone to use.
