DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is mainly intended to draw attention to a straight-ahead vehicle or a pedestrian at the time of right or left turn by mainly displaying the side and length of the vehicle body of a large vehicle at night. The present invention relates to an optical display device for an automobile wheel.

[0002]

2. Description of the Related Art Generally, large vehicles at nighttime driving, particularly,
When a large vehicle such as a trailer with a long vehicle body turns right or left, the headlights and vehicle side lights alone do not provide sufficient caution to the driver of a straight ahead vehicle. For this reason, a device has been devised to appeal for the presence of the vehicle by means of illumination or the like, but this is not sufficient as a caution display.

[0003]

SUMMARY OF THE INVENTION The present invention has been made based on the above circumstances, and it is an object of the present invention to provide a sufficient warning display to a driver or a traveling vehicle on a straight ahead vehicle when turning right or left. Yes, and the body length has been confirmed,
Provided is an optical display device for a wheel of an automobile, which recognizes the passage of a vehicle at an intersection and is effective for displaying a warning to pedestrians on a road.
