Abstract

A sudden-stop brake-light warning system (10) that causes the brake lights (56) of a vehicle to intermittently pulse when the brake pedal is suddenly depressed as in a panic stop. The pulsation of the lights (56) is achieved by a flashing brake-light circuit (12) that is only activated during a panic stop. The circuit (12) consists of a mercury switch (51), located in an inertia operative switching circuit (16), that closes only when the brake switch (54) is suddenly depressed. When the switch (54) closes, the power from the vehicle battery (52) is applied to the gate of a silicon controlled rectifier (CR1) located in a silicon controlled rectifier circuit (18). The energizing of CR1 enables a multivibrator circuit (14) connected via a relay driven transistor (Q3) to the coil (20A) of a relay (K1) located in a relay drive/relay circuit (20). The relay is pulsed in accordance with the time constant of the multivibrator and as the coil (20A) pulses, so are the brake lights (56).
