Lighting Compatibility and Key Functions

• 7-pin Trailer Electronics Module – suitable for universal trailer light connection for 7-pin plug systems.
• Advanced Signal Management – in addition to basic light control, the module offers more control and additional functions than simpler solutions.
• Support for LED and Incandescent Bulbs – compatible with vehicles using both LED and standard bulbs.
• PWM Support – works with vehicles where lighting is controlled via Pulse Width Modulation.
• Designed for Light Trailers – the 7-pin solution is primarily intended for light trailers where a reverse light circuit is not required.

Convenience and Installation

• Complete Installation Kit – includes wiring, socket, and mounting accessories for a simpler and faster installation.
• Socket Connected to Main Wiring – helps shorten installation time and makes the kit more convenient to use.

Safety and Operating Features

• Low Input Load – does not overload the vehicle's original electrical system and is suitable for modern vehicles.
• Trailer Detection – the module can detect a connected trailer and provide notification via an acoustic signal.
• Turn Signal Failure Notification – alerts about a trailer turn signal bulb failure with an acoustic signal.
• Sequential Fog Light Control – offers a smarter fog light control logic.
• Additional Control Option – an optional separate LED indicator can be used to display trailer connection and error messages.
• 7-pin System – please note that the 7-pin plug does not include a reverse light output.
