Directional signal switch and alternating lighting of rear lamps
First Claim
1. A turn signal switching circuit for an automotive vehicle, said vehicle having an ignition switch with an output terminal, first and second turn signal and brake lamp circuits each having at least one front turn signal lamp, rear turn signal and brake lamp on opposite sides of said vehicle, each of said lamps have first and second element connections comprising:
- a flasher element having an input connection connected to the output terminal of said ignition switch and an output connection;
a common electrical ground;
a battery having a positive and negative terminal, said positive terminal connected to the input terminal of said ignition switch and said negative terminal connected to said common electrical ground;
a turn signal switch interconnected between the first element connection of said front and rear turn signal lamps and brake lamps circuits and the output connection of said flasher element for selectively connecting one of said turn signals and brake lamp circuits to the output connection of said flasher element;
switching means mechanically interconnected to said turn signal switch for operation therewith and electrically interconnected between the output terminal of said ignition switch and the second terminal of the rear turn signal lamp on each side of said vehicle; and
said second element connection of said brake lamp and front turn signal lamp on each side of said vehicle is connected to said common electrical ground,said turn signal switch and mechanically interconnected switching means acting, when operated for lamp illumination on a selected side of said vehicle to illuminate said rear turn signal lamp alternately with illumination of said brake, and front turn signal lamps on said selected side of said vehicle.

Abstract
Directional signaling for automobile vehicles in which vehicle turning is indicated by the flashing of the front turn signal lights and the alternate flashing of the combined brake and rear turn lights. A key operated ignition switch is provided that renders the battery voltage off all direction signaling circuits in the "off" position, allows all directional circuits to be energized with battery voltage in the "on" and the "accessory" positions and permits the key to be removed in both the "off" and "accessory" positions. In one embodiment, relay operated switches in conjunction with a conventional flasher unit provide selective flashing of the left or right signal lamps and disconnects brake lamp illumination on the turn signal activated side. The brake light switch is rendered ineffective when the stop lights are being used as turn signals. In another embodiment, the brake lights are utilized in combination with backup lamps.
