     FIELD OF INVENTION 
       [0002]    The present invention generally relates to a vehicle light, and more particularly, to a system, method, and apparatus for configuring a marker light to function as one or more of a marker light, Center High Mount Stop Lamp (CHMSL), or brake light. 
       BACKGROUND 
       [0003]    A marker light or device on a vehicle promotes visibility to the vehicle, The marker light is typically located on the sides of vehicles less than 80 inches wide and on the back and sides of vehicles greater than 80 inches wide. 
         [0004]    A Center High Mount Stop Lamp (or Light) (CHMSL) is a central brake lamp (or light) on a vehicle that is typically mounted higher than the left and right brake lamps on the vehicle. The CHMSL (also known as center brake lamp, third brake lamp, eye-level brake lamp, safety brake lamp, high-level brake lamp, Dole light, or Liddy light) is required in some countries. 
         [0005]    In the past, one or more marker lights or devices (e.g., located on the back of the vehicle) and a standard stop light (e.g., located near the lower rear end of the vehicle) have been used on various vehicles. The U.S. government, for example, has required that all vehicles under 80 inches wide have a CHMSL. See Title 49 of the Code of Federal Regulations, Chapter V, Section 571.108, which is incorporated by reference. All vehicles 80 inches or more wide do not require a CHMSL, but require three high mount marker lights in the center at the top of the vehicle. 
         [0006]    It is desirable to improve the marker lights, CHMSLs, and brake lights that already exist on most vehicles.

     DETAILED DESCRIPTION 
       [0034]    It is desirable to improve the marker lights, CHMSLs, and brake lights that already exist on most vehicles. The present invention adds a safety feature to such vehicles by incorporating circuitry into a marker light to allow the marker light to function as one or more of a marker light, a CHMSL, and/or a brake light to aid in warning any drivers behind the vehicle of any braking or slowing down of the vehicle in front of them. 
         [0035]    In an exemplary embodiment of the present invention, even though not required by law at this time, by modifying the marker light to control the function of one or more of a marker light, CHMSL, or brake light for vehicles less than, greater than, or equal to 80 inches wide, all vehicles can easily include marker lights, CHMSLs, and brake lights without the need to add CHMSLs (which vehicles greater than or equal to 80 inches do not currently have). In addition, for vehicles less than  80  inches wide, the CHMSL can be replaced by a modified marker light  101  of  FIGS. 1 ,  11 , and  12  of the present invention, so that such vehicles can include one light that functions as both a CHMSL and a marker light. By adding modified marker light  101  of the present invention, every vehicle that does not have a CHMSL can have a CHMSL without the need to add an additional light or LED. By adding the function of a CHMSL to all vehicles, a driver behind the vehicle receives additional warning of the vehicle braking By adding modified marker light  101  of the present invention, every vehicle that does not have a marker light can have a marker light without the need to add an additional light or LED. By adding the function of a marker light to all vehicles, a driver ahead of the vehicle or otherwise near the vehicle receives additional warning of the vehicle ahead or near it. The terms “marker light” or “modified marker light” can include at least one of a marker light, a CHMSL, a brake light, a turn signal light, a running light, a tail light, a head light, or any other type of light used on a vehicle (or a plurality of these). 
         [0036]    The present invention includes configuring modified marker light  101  to control the function of one or more of a marker light (not shown), Center High Mount Stop Lamp (CHMSL) (not shown and brake light (not shown). Modified marker light  101  consolidates and improves the function of these lights, which increases visibility of a vehicle (not shown) and promotes vehicular safety. Modified marker light  101  has circuitry  103  that can be incorporated into the circuitry of a typical marker light, a Center High Mount Stop Lamp (or Light) (CHMSL), and/or a brake light of a vehicle. Modified marker light  101  has circuitry  103  that can energize a typical marker light, CHMSL, and/or brake light when the vehicle stops, brakes, or slows down without the need to add a CHMSL to vehicles that do not have a CHMSL. Modified marker light  101  can be used with vehicles and/or trucks that are greater than less than, or equal to 80 inches in width. 
         [0037]    Using circuitry  103  in modified marker light  101 , a high mount stop light (e.g., CHMSL), marker light, and/or brake light is multi-functional compared to a traditional marker light, brake light, or CHMSL on a vehicle. Modified marker light  101  allows for additional warning signals to people following the vehicle to have more time for braking and/or stopping. For example, marker lights are typically not turned on, unless the headlights of a vehicle are turned on However, with modified marker light  101 , when a driver activates the brakes, modified marker light  101  functions as a CHMSL even for a vehicle that does not have a CHMSL, In other words, for vehicles that do not have a CHMSL, but have modified marker light  101 , modified marker light  101  can function as a marker light, a CHMSL, or both without having to add additional lights or light emitting diodes (LEDs) to a vehicle, Modified marker light  101  can meet the federal U.S. legal requirements for marker lights (e.g., for vehicles equal to or greater than 80 inches in width), meet the federal U.S. legal requirements for CHMSLs (e.g., for vehicles less than 80 inches in width), and allow for universal operation of brake lights, all using the same circuitry  103  in modified marker light  101 . 
         [0038]    In an exemplary embodiment, if headlights of a vehicle are on (e.g., via a running light circuit (not shown)) and the driver activates the brakes (not shown) on the vehicle (e.g., using a brake light circuit  105 ), circuitry  103  of modified marker light  101  allows for marker lights (that may already be illuminated) to illuminate brighter as a warning to a vehicle behind this driver. In an exemplary embodiment, if headlights of a vehicle are off and the driver activates the brakes on the vehicle (e.g., using the brake light circuit), modified marker light  101  allows for marker lights (that may not be illuminated) to illuminate as a CHMSL as a warning to a vehicle behind this driver. In an exemplary embodiment, circuitry  103  for a CHMSL can be incorporated into the existing circuitry of a marker light to create modified marker light  101  to allow for a CHMSL to be used for vehicles greater than or equal to 80 inches wide without adding an additional light or LED. 
         [0039]    This universal functionality of modified marker light  101  to be used as a typical marker light, a CHMSL, or both without the need for adding any additional lights or LEDs to a vehicle: 1) enhances safety by warning a driver that a vehicle is slowing down or stopping in front of the driver and 2) is cost efficient by removing the need for vehicles without a CHMSL to add a CHMSL to the vehicle. In the past, only vehicles under 80 inches in width required a CHMSL and only vehicles greater than or equal to 80 inches in width required marker lights. As such, substantially all vehicles greater than or equal to 80 inches in width do not have a CHMSL. In this way, one light has been used as a marker light, but a light would need to be added to such vehicles to function as a CHMSL. Modified marker light  101  with functionality of both the CHMSL and marker lights provides a universal control that can be used on substantially all vehicles. Using this modified marker light  101 , vehicles can have one light to function as marker lights, CHMSLs, and/or brake lights that can operate individually or simultaneously without the need for adding additional lights or LEDs to a vehicle. Modified marker light  101  allows for multi-use lights that can increase visibility of the vehicle to other drivers or passengers when the driver is stopping or braking without the need for multiple lights or LEDs on the vehicle. 
         [0040]    In an exemplary embodiment, in  FIGS. 2-4 ,  11 , and  12 , modified marker light  101  includes three prongs, one prong  202  for coupling to a CHMSL (or brake light), a second prong  204  for coupling to one or more marker lights (or marker light circuitry), and a third prong  206  for coupling to ground. Modified marker light  101  includes a first input  202  (e.g., e.g., high mount stop light input) coupled to a CHMSL (and/or brake light), a second input  204  (e.g., marker light input) coupled to one or more marker lights, and a third input  206  coupled to ground. 
         [0041]    In  FIG. 5 , circuitry  103  of modified marker light  101  includes a first diode (D 1 )  502  coupled between first input  202  and a first resistor (RA 1 )  504 .

Third light emitting diode  514  is coupled between second light emitting diode  512  and a ground  516 .
