Abstract
Abstract An automobile signal system, having three modes of operation, stop, caution, and go. All three modes are energized by the automobile battery when the ignition switch is closed. The caution mode will operate only when neither the gas or brake pedals are pressed. The stop mode utilizes a relay to isolate its circuitry from that of the caution mode. The go mode utilizes a switch which is activated by an accelerator sensitive member.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
171 words
An automobile signal system comprising: (a) a stop mode circuitry; (b) a caution mode circuitry; (c) a go mode circuitry; (d) said stop, caution, and go modes circuitry all being capable of being energized by the automobile battery when the ignition switch is closed; (e) said stop mode circuitry utilizing a red lamp, operative by means of the automobile brake pedal, said caution mode circuitry utilizing an amber lamp, and said go mode circuitry utilizing a green lamp operative by means of the automobile gas pedal; (f) circuit means for interconnecting said caution mode circuitry as to be operational whenever neither the gas pedal nor the break pedal is pressed; (g) said stop mode circuitry utilizing a relay to isolate its circuitry from the caution mode; (h) said go mode circuitry utilizing a switch which is activated by an accelerating sensitive member, and (i) circuit interconnection means between said stop mode circuitry and said go mode circuitry for preventing both the red lamp and the green lamp from being operated simultaneously.
