  • Patent number: 4812808
    Abstract: An electronic control circuit in a control system for lights including a storage battery having two terminals with one terminal being connected to ground and another terminal connected to a flasher means. The control system further includes a left and right rear tail light, a left and right front running light, a right rear and left rear brake light, a left and right turn indicator light, a left and right turn switch, an emergency switch, and a brake light switch. The electronic control circuit includes in combination, an operating circuitry board; and an emergency circuitry mounted on the operating circuitry board. A right turn and left turn circuitry is mounted on the operating circuitry board. A brake light circuitry is also mounted on the operating circuitry board as well as a tail light circuitry.

  • Patent number: 4670736
    Abstract: An electronic control circuit has in combination, an operating circuitry board; and an emergency circuitry mounted on the operating circuitry board and in electrical communication with the battery and the emergency switch. The emergency switch when activated causes the emergency circuitry to send intermittent electrical power from the battery to the left and right front and rear lights causing the same to flash on and off intermittently. A right turn circuitry, a left turn circuitry, a brake circuitry, and a taillight are mounted on the operating circuitry board. A method for controlling lights include mounting the following circuits on an operating circuitry board: an emergency circuitry; a right turn circuitry; a left turn circuitry; a brake circuitry; and a taillight circuitry.
