Automatic light switching unit for LEDs

The SK-CD105 is an intelligent control module designed for eagle eye LED daytime running lights (DRL) or other LED DRL modules. It offers automatic DRL on/off functions when the low beam is turned on and a practical departure mode with a delay after the engine is turned off. It protects the car battery by monitoring the voltage and allows for easy installation without complex electronics.

Functions and features

• Automatic DRL lighting when the engine is started if the voltage reaches ≥ 13 V.
• Automatic DRL shutdown when voltage drops below 12.5 V, with the option to extend the lighting time if voltage remains higher.
• Departure mode – DRLs remain on for approximately 15 seconds after the engine is turned off for safe exit from the vehicle.
• Possibility to dim the DRL to half brightness when turning on the dipped beam or reading lights (by connecting the yellow wire).
• The SK-CD105 model allows you to completely turn off the DRL when turning on the low beams.
• Easy installation directly on the vehicle battery with integrated fuse.
