     FIELD OF THE INVENTION 
     The present invention pertains to the field of motor vehicles, and more specifically to the field of safety accessories. 
     BACKGROUND OF THE INVENTION 
     Every year, thousands of Americans find themselves stranded on the side of the highway. Whether a blown tire, a leaking radiator or other mechanical or electronic failure, such vehicular mishaps can occur without a moment&#39;s notice and leave a motorist helpless and vulnerable. In addition to annoyance and frustration of car trouble inspires, being stranded can be a frightening and dangerous situation. Particularly, mothers with a carload of small children, young drivers, and elderly motorists often are ill prepared to figure out the mechanical intricacies of a stalled vehicle and lacking in knowledge and equipment to take care of the problem on their own. 
     Stranded drivers are at the mercy of passing motorists to offer them roadside assistance. Due to increased concerns for personal safety, motorists are much less likely to stop and help a stranded stranger than in the past. While a cellular telephone usually is invaluable in these situations, sometimes break downs occur in an area with no cellular service, or a cell phone loses battery charge and is dead. At this point is necessary to leave one&#39;s vehicle to flag down assistance, but many times it is unsafe or impractical to do so if stranded on a major highways, at night, in the cold, or with children in the vehicle. In addition to mechanical failure, a stalled vehicle may contain a motorist who is experiencing a medical emergency. Unable to safely drive, this individual may find himself helpless to alert passing cars that he is in dire need of assistance. 
     The prior art has put forth several designs for safety accessories. Among these are: 
     U.S. Pat. No. 7,378,948 to Eddie Somuah describes a digital message display for vehicles that detects a tailgater and automatically flashes a warning message directed to the tailgater. The message displays on an electronic board located in the rear window of the vehicle in view of following traffic. In addition to the warning message directed to the tailgater, a distance display is located in view of the vehicle driver to indicate the distance of the tailgater. An audible alarm alerts the driver to the presence of the tailgater. A wireless remote control device allows the driver to manually select and display one of a number of predefined safety and courtesy messages. Multiple distance sensors provide multiple functional ranges to accommodate varying driving or traffic conditions. 
     U.S. Pat. No. 6,553,285 to Reslan Bahmad describes a message conveying system for motor vehicles that allows a person operating a vehicle to display one of a plurality of messages to other motorists including a message display adapted for positioning within a motor vehicle adjacent to a rear window thereof. The message display includes an alphanumeric screen disposed therein. The message display includes an internal message memory therein for storing a plurality of alphanumeric messages therein. The internal message memory is in communication with the alphanumeric screen. The message display includes an internal message selection control in communication with the internal message memory. A remote control unit is adapted for securement to a dashboard of the motor vehicle. The remote control unit is in communication with the message display. The remote control unit includes a plurality of message buttons. The message buttons each correspond with one of the plurality of alphanumeric messages of the message display whereby pressing one of the message buttons will allow one of the alphanumeric messages to be displayed on the alphanumeric screen. 
     U.S. Pat. No. 5,500,638 to Ikoma A. V. George describes a method of communication between vehicle operators. The invention employs common display LEDs, the segments of which, when appropriately turned on, issue desired messages on the reader board for the operators of other vehicles. To issue a message, the operator of a vehicle simply depresses a button on the control box. The operator of a vehicle behind sees the message for a length of time set by a programmable timer. 
     None of these prior art references describe the present invention.
