Description:
BACKGROUND OF THE INVENTION 
     The present invention relates to an open type vehicle such as a motorcycle, bicycle or scooter provided with an illuminating lamp means particularly for securing the safe driving thereof at sunset or night. 
     A vehicle such as motorcycle, bicycle or scooter is often driven at sunset or night while illuminating a head light to secure safety of the front portion. The bicycle is equipped with a reflecting plate at a rear portion of the bicycle body so that a vehicle such as automobile running behind the bicycle can discriminate the existence of the bicycle and maintain a proper distance between the vehicle and the bicycle for the sake of safety. The motorcycle is provided with a numberplate lamp or flasher lamp at the rear portion thereof for the same purpose. 
     Furthermore, with respect to a motorcycle such as a police motorcycle, a rider wears a jacket, to a back portion of which is applied a V-type fluorescent light reflecting band so that the existence of the police motorcycle is discriminated by vehicles driving behind the same. 
     As described above, conventional motorcycles or bicycles are equipped with rear light reflecting plates or other like members or means so that vehicles running behind the motorcycle or bicycle can discriminate the existence thereof for securing safe driving. 
     However, it will be said that these conventional members or means attached to the motorcycles or bicycles cannot sufficiently attain their functions for discriminating the existence of motorcycles or bicycles with respect to the vehicles running behind them. Furthermore, the V-type fluorescent light reflecting jacket of the rider on a police motorcycle can attain its function only by reflecting the light from the vehicle running behind the police motorcycle and, accordingly, this function will not be attained in a case where the vehicle running behind the police motorcycle is not equipped with a lighting means. 
     SUMMARY OF THE INVENTION 
     An object of the present invention is to substantially eliminate the defects or disadvantages encountered in the prior art and to provide an open type vehicle such as motorcycle or bicycle provided with an illuminating means for discriminating the existence of the vehicle to other vehicles or pedestrians behind the vehicle during driving at night. 
     This and other objects can be achieved according to the present invention by providing an open type vehicle such as motorcycle or bicycle having a vehicle body characterized in that an illuminating means is arranged at a rear portion of the vehicle body for illuminating the back of a rider on the vehicle. 
     The illuminating means may be arranged at various portions of members or portions of the vehicle such as motorcycle or bicycle suitable for illuminating the back of the rider sitting on the seat of the vehicle. 
     According to the open type vehicle of the character described above, the illuminating means illuminates the back of a rider during the driving at night time to bring the back of the rider into relief to inform the existence of the open type vehicle to vehicles or pedestrians behind the open type vehicle, thus securing the safe driving thereof.
