Description:
BACKGROUND OF THE INVENTION 
       [0001]    1. Field of the Invention 
         [0002]    The present invention relates to an automobile light emitting device, not only reducing car accidents, but also providing a warning effect to improve the safety of drivers and passengers. 
         [0003]    2. Brief Description of the Related Art 
         [0004]    A blinking signal light is provided for warning and reminding nearby passengers, bicycle riders or motorcycle riders while a car is making a turn, and preventing accidents when the car is getting too close. However, nearby passengers, bicycle riders or motorcycle riders have to pay attention to the conditions of the road ahead and may not be able to notice a car in another lane getting ready for a street parking or making a left or right turn under a poor visual condition or an over-speed condition, and people may be injured in all kinds of car accidents. 
         [0005]    Furthermore, car owners may not be able to locate the position of their car in a large parking lot or a mall. Although beep sounds or lit signal lights are provided for reminding the car owners, the exact position of the car cannot be located easily if the owner&#39;s car is blocked by other cars. 
         [0006]    In poor weather conditions such as heavy rain, a driver may enter into the car and open the locks of all car doors, but passengers have no way to find out from the outside that the doors are opened already, and the passenger has to ask the driver or the driver has to tell the passenger. As a result, the passenger has to stand in the rain for a while or get wet before entering the car. 
         [0007]    Obviously, it is necessary to overcome the aforementioned drawbacks by providing an automobile light emitting device to remind passengers about a car at the front is making a turn to improve the road safety and provide a way to inform passengers about the door lock is opened already and allow the passengers to enter into the car quickly. 
       SUMMARY OF THE INVENTION 
       [0008]    Therefore, it is a primary objective of the present invention to provide an automobile light emitting device, comprising a plurality of light emitting members, a control unit and an electric connection circuit, wherein each light emitting member is installed at a peripheral surface (such as a fender, a wheel arch panel or a wheel housing panel) outside an automobile wheel, a door handle or a door handle recess of a car door, or a car roof (such as a car antenna, a convertible top rack or an automobile shark fin). 
         [0009]    The control unit with a signal light control circuit is provided for controlling a right-turn signal light to blink, such that when the right-turn signal light blinks, the light emitting members installed on corresponding fenders of at least two right wheels also blink, and when the signal light control circuit controls a left-turn signal light to blink, the light emitting members installed on the corresponding fenders of at least two left wheels also blink. Such arrangement can remind passengers, bicycle riders or motorcycle riders to watch out for any car which is ready to make a turn or a street parking, in order to avoid car accidents and improve the road safety of the passengers. 
         [0010]    Alternatively, the control unit is linked to a central lock control unit of a car, and the control unit turns on the light emitting member to actively notice that the door lock is opened when the central lock control unit controls and opens the door lock, so that passengers can open the car door and enter into the car immediately, so as to save time and physical strength of the passengers, particularly in poor weather conditions such as a hot sunny day or a rainy day in an outdoor car park without any shelter.
