Abstract: The present invention relates to an automotive device which will control the operation of optional tail lights equipment by monitoring level of current in any motor vehicle OEM tail lights electrical circuit. The device comprises a plurality of current sensor modules, each including a current sensor and a RF transmitter antenna, and a brain module including a controller, a RF receiver antenna, and a power source. The current sensors are placed on top of OEM tail lights wire to monitor the current level and transmit such information to brain module. When the level of current detected by any current sensor raises above certain level the controller closes electrical circuit of the optional tail light equipment dedicated to that particular Sensor; when the level of Current lowers under certain level, the controller opens the electrical circuit of the optional tail light equipment dedicated to that particular Sensor.
