The automatic unit reacts to a voltage spike when starting the engine in the car. The daytime running lights turn on automatically when the engine is started and dim (up to 30%) when the side and dipped headlights are turned on.

The device was manufactured in Poland by ALTIM-PLUS. It is used to automatically turn on and off the passing and parking lights or LED daylights. This will help you avoid paying fines for driving without lights and make you safer and more confident on the road.
