TRAILER LIGHTS CONTROL UNIT
MP3S
INSTALLATION MANUAL
GENERAL FUNCTION DESCRIPTION
GENERAL FUNCTION DESCRIPTION
The module is designed to control the trailer lighting system.The car rear light voltages are used to drive the
controller module. The module inputs should be connected to the car rear lights driving wires according to
required trailer lighting driving pattern. The module inputs for correct operation require only around 1 mA
each (a 5W bulb is drawing 0.5 amp) and total current consumption does not activate overload sensing
modules in the car’s lighting system. The module will activate required lights on the trailer after receiving
input driving signal.
The controller can also work with electric installations in the cars where some of the lights perform two light
intensity functions based on PWM (pulse width modulation) technique.
The module is provided to control a lighting of the trailer through 7-pin trailer socket.
