At TTS we now also make modules to allow existing LED lights to be dimmed. The normal function is of course also retained.
You can use this to let LED fog lamps and spotlights, etc., burn as city lights without having to drill separate lights or fittings. 2 to 4 lamps can be connected to it and dimmed as required. They also continue to work as a bright spotlight. Very well applicable to original LED lamps as applied to, among other things. Scania next gen.
