Abstract
An emergency brake illumination system for a trailer illuminates the trailer brake lamps upon application of the emergency brakes. The system includes a pressure switch which senses pressure in the emergency brake system. The pressure switch is electrically connected between the blue circuit and the red circuit of a seven-way connector. If a loss of pressure is sensed by the pressure switch, the switch closes and power is provided by the blue circuit to the red circuit to illuminate the brake lamps.
