Description:
BACKGROUND OF INVENTION  
       [0001]     The present invention generally relates to warning systems and, more particularly, to an improved auxiliary vehicle warning device capable of being placed on the roof of the vehicle as and when required and could be removed from the said place when the use of the same is over.  
         [0002]     In all countries there is an increasing number of automobiles and other types of motor vehicles, such as trucks, vans and delivery vehicles that are crowded onto increasingly crowded roadways. There are basically two types of situations encountered by modern vehicles, first there is the high speed travel encountered on toll roads, freeways or interstate highways and second, there is the congested, crowded travel encountered mainly in cities and suburban areas. In either situation, it is becoming more and more important to increase the safety of travel to improve the quality of travel for all travelers.  
         [0003]     Because of the high-speed travel encountered in the first situation and the congested and crowded travel encountered in the second situation it is important that as much information as possible concerning operation of a vehicle be communicated to other vehicles. In addition, it is important that as much information as possible be communicated to following vehicles concerning conditions the following vehicles will encounter. This information must be communicated quickly and easily and be clear and concise.  
         [0004]     In view of the large number of vehicles which become disabled on the road, there is also a substantial need of an improved “disabled condition” signaling system which can be operated from the inside of the vehicle and which will be visible at a considerable distance. Such device preferably also should be capable of transmitting to drivers of other rear vehicles and other messages, such as warning to the high speed rear vehicle to slow down the speed, car stuck due to break down, call for help in need of emergency.  
         [0005]     Over the years, many vehicle communication devices have been proposed including, in the most basic forms, fixed signs bearing appropriate messages. More recently, several signaling or communication devices have been suggested having the capability of individual selection of one of a plurality of messages for viewing externally of the vehicle. For instance, such messages may include a request of a following driver to dim lights or to avoid tailgating, to notify a following driver of road or traffic conditions ahead, to request passing drivers to send help or render assistance in an emergency, etc. Most recently, several message or communication devices have been suggested having a control unit in which messages can be programmed together with a display unit for a programmed message. However, in nearly every instance, such devices suffer from one or more serious drawbacks rendering them less than fully desirable.  
         [0006]     In particular, such devices have usually been designed to sit on the rear deck of a vehicle in the rear window for viewing by a following motorist. This is most undesirable, however, because it interferes with normal use of an inside rearview mirror. The size and construction of such devices, as exemplified by U.S. Pat. Nos. 4,361,828 and 3,299,552, among others, create blind spots that could result in a serious accident by reason of a driver failing to see another nearby vehicle, for example, during a lane-changing maneuver. This is not a problem, however, in some of the communication devices proposed in earlier times. Unfortunately, devices such as those proposed in U.S. Pat. Nos. 2,843,952 and 2,503,336 suffer from other serious drawbacks.  
         [0007]     In particular, the latter devices are adapted to be mounted externally of a vehicle. This either requires some permanent modification to the vehicle or greatly restricts the ability of a motorist to add the device as an aftermarket accessory and, in any event, is subject to theft, breakage, or damage or obstruction by adverse weather and road conditions. Moreover, the installation of such devices is well beyond the usual capabilities of the average motorist.  
         [0008]     The various systems for automobile-to-automobile communication have been proposed. Generally, these involve the signaling of preselected messages from one vehicle to another in response to the manual operation of a switch to select the message to be communicated. These systems typically do not interface with the standard vehicle signaling devices. Other simple communicating devices include fixed signals with appropriate messages that are displayed somewhere on the vehicle. Some of the proposed methods include messages that are pre-programmable to be displayed at the rear of the vehicle. However, one of the problems in existing systems is that when these fixed signals are displayed there is a potential for confusing signals to be sent. There can be conflicting signals sent by the communications system to the drivers of other vehicles when the automatic signals are displayed, such as break lights or turn signals. For example, the driver of a vehicle may be displaying a fixed sign such as “SAFE TO PASS ON RIGHT”, when an emergency braking situation occurs. The driver presses the break pedal and does not have time to remove the displayed fixed sign. This situation clearly has the potential to confuse a following driver and may cause an accident.  
         [0009]     Despite the many attempts to overcome the problems with signaling, message and communication devices, it has remained to provide a truly universal vehicle communicator capable of satisfying the requirements of motorists in an effective manner.  
         [0010]     Accordingly, in order to improve vehicle driving safety there is a need for an improved, inexpensive, durable auxiliary visual vehicle warning device capable of being easily and detachably mounted at top of a vehicle and at a desired eye level. Such device preferably should utilize existing vehicle circuitry and be capable of being installed by any vehicle driver with few or no tools in a minimum amount of time.
