Abstract

An ABS/ESC activated brake light device includes a first connector, a second connector, an antilock brake system and/or electronic stability control (ABS/ESC) signal detection circuit connected to the first connector, a control circuit connected to the ABS/ESC signal detection circuit, a brake light signal generation circuit connected to the control circuit and the second connector, and a power supply. The first connector is configured to plug into an antilock brake system pump motor circuit on a fuse panel of a vehicle. The second connector is configured to plug into a brake light circuit on the fuse panel of the vehicle. The control circuit sends one or more control signals to the brake light generation circuit whenever an ABS/ESC signal is detected. The brake light signal generation circuit causes the brake lights of the vehicle to flash whenever the one or more control signals are received from the control circuit.
