## Background
1. Field of the Invention

This invention is related to an improved method and electronic control circuit for controlling lights.

2. Description of the Prior Art

U.S. Pat. No. 3,909,661 to Grossenbacher discloses an electronic control for automobile lights. U.S. Pat. No. 3,621,329 by Frey teaches a combined system wherein the lights are multifunctional for both parking, boundary and tail lights which may be energized when the system is in operation. U.S. Pat. No. 4,223,375 by Alpen discloses a headlight system for motorcycles. None of the foregoing prior art patents teach or suggest the particular improved electronic control circuit of this invention.

This invention broadly accomplishes its desired objects by broadly providing an electronic control circuit in a control system for lights having a storage battery means with two terminals, one terminal being connected to ground and another terminal connected directly 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, and a left and right turn signal and indicator light. The control system additionally has a left turn switch means connected between the storage battery means and the left turn signal and indicator light, and a right turn switch means attached between the storage battery means and the right turn signal and indicator light. An emergency switch means is connected between the left rear brake light and tail light and right rear brake light and tail light. A brake light switch means is connected between the storage battery means and the left and right rear brake lights. The electronic control circuit comprises in combination, an operating circuitry board; and an emergency circuitry means mounted on the operating circuitry board and in electrical communication with the battery means and the emergency switch means. The emergency switch means when activated causes the emergency circuitry means to send intermittent electrical power from the battery means to the left rear brake lights and tail lights and right rear brake lights and tail lights causing the same to flash on and off intermittently. A right turn circuitry means is mounted on the operating circuitry board and is in electrical communication with the battery means and the right turn switch means. The right turn switch means when activated causes the right turn circuitry means to send intermittent electrical power from the battery means to the right turn signal and indicator light. A left turn circuitry means is mounted on the operating circuitry board and is in electrical communication with the battery means and the left turn switch means. The left turn switch means when activated causes the left turn circuitry means to send intermittent electrical power from the battery means to the left signal and turn indicator light. A brake like circuitry means is mounted on the operating circuitry board and is in electrical communication with the battery means and the brake light switch means. The brake light switch means when engaged causes the brake circuitry means to send electrical power from the battery means to the left and right rear brake lights. The electronic control circuit further comprises a tail light circuitry means mounted on the operating circuitry board and in electrical communication with the battery means. The tail light circuitry means sends electrical power from the battery means to the left and right rear tail lights, to the left and right front running lights, and to the left and right rear brake lights. It is therefore an object of this invention to provide an improved electronic control circuit.

Still further objects of the invention reside in a provision for an improved electronic control circuit that eliminates many of the wires and lights on a motorcycle, or the like.

These together with the various ancillary objects and features will become apparent as the following description proceeds, are attained by this invention, preferred embodiments being shown in the accompanying drawings, by way of example only, wherein:

Referring in detail now to the drawings wherein similar parts of the invention are identified by like reference numerals, there is seen my electronic control system, generally illustrated as 8, which has two preferred embodiments respectively illustrated in FIGS. 2 and 3.

It should be initially understood that my electronic control system 8 may be utilized in any lighting system where it is desirable to eliminate many of the wires and lights without loosing any of the preexisting advantages and functionalities. Preferably, my electronic control system 8 is utilized in a preexisting motorcycle electronic control system for motorcycle lights. My system 8 ties into an existing motorcycle factory electronic control box, generally illustrated as 9 in FIG. 1, and controls and/or regulates on a motorcycle a left rear light 10, a right rear light 12, a left front light 14, and a right front light 16. In the preferred embodiment of FIG. 3, my electronic control system 8 also controls a plurality of motorcycle running lights which are not shown in the drawings because the number and position of the motorcycle running lights vary with the brand of motorcycle. In both preferred embodiments of my electronic control system 8, the left rear light 10 and the right rear light 12 function as brake lights, tail lights, left and right turn lights, and emergency lights. Any existing brake lights, tail lights turn lights and emergency lights may be eliminated on a motorcycle, along with the numerous wires associated therewith, and replaced with the left rear light 10 and the right rear light 12 and a single set of wires for same.

An existing motorcycle electronic control system would include an ignition switch 18, a storage battery 20 having tow terminals with one of the two terminals grounded, a left and right turn switch, an emergency or hazardous switch, brake switch which is activated when the brakes are engaged, and a tail light switch which may also activate a head light and running lights. None of the switches are shown in the drawings as they are well known to artisans in the art.

When my electronic control system 8 is electrically engaged with the electronic control box 9 and between the left rear light 10 and right rear light 12 as illustrated in FIG. 1, the left turn switch is electrically connected between the storage battery 20 and the left rear 10 and the left front 14 lights, and the right turn switch is electrically attached between the storage battery 20 and the right rear 12 and right front 16 lights.

In the embodiment of FIG. 3 where running lights exist, the running light switch (or the tail/running light switch where the tail light switch functions to activate both the tail lights and the running lights) is electrically connected between the storage battery 20 and the running lights.

The preferred embodiment of my electronic control system 8 in FIG. 2 comprises an operating circuitry board 22. An emergency circuitry means is mounted on the operating circuitry board 22 and is in electrical communication with the battery 20 and the emergency switch means. When the emergency switch means is activated, it causes the emergency circuitry means to send intermittent electrical power from the battery 20 to the left 14, 10 and right 16, 12 front and rear lights, respectively, causing the same to flash on and off intermittently. A right turn circuitry means is mounted on the operating circuitry board 22 and is in electrical communication with the battery 20 and the right turn switch means. When the right turn switch means is activated, it causes the right turn circuitry means to send intermittent electrical power fron the battery 20 to the right front 16 and right rear 12 lights. A left turn circuitry means is also mounted on the operating circuitry board 22 and is in electrical communication with the battery 20 and the left turn switch means.
