First Claim
1. An auxiliary signal system for automobiles of the type including a main signal system defined by front and rear, right and left stop and amber turn indicators, and a flasher for indicating an emergency, said auxiliary signal system comprising relay means for connection to the main signal system to supply power to the auxiliary system and to render the main signal system inoperative when the auxiliary system is operating, auxiliary flasher means for supplying power alternately to the left and right vehicle turn indicators when the relay means is activated;
- timer means connected to said relay means for controlling the duration of operation and automatic shut-off of the auxiliary system;
control circuit means connected to and receiving power from said main signal system and from the vehicle brake system, said control circuit means incorporating said relay means and said timer means for controlling operation of said flasher means, whereby actuation of the vehicle brakes and of the control circuit means by a driver causes alternating flashing of the vehicle front and rear turn indicator lights which continues for a predetermined period of time after the brake pedal is released.

Abstract
An auxiliary pedestrian crossing warning signal system for use in automobiles equipped with a main signal system including front and rear, left and right amber turn indicator lamps incorporates an alternating flasher into the main signal system via a relay to provide communication between a driver and a pedestrian in order to reduce vehicle-pedestrian collisions. An automatic shut-off timer is connected to the relay circuit for controlling the duration of the auxiliary system operation after the brake pedal is released. The auxiliary system is operated by a momentary pressure on a pushbutton switch mounted in the dashboard and by the application of pressure to the vehicle brake pedal, so that the auxiliary system operates only when the pushbutton is energized and the vehicle is stopped. In addition to the in-dash indicator lights, a pair of indicator lights can be mounted beside the pushbutton switch as an additional indication that the auxiliary system is in operation.
