Abstract

An information indicating device having an LED and a light transmitting structure is disposed within a line of sight of a vehicle operator so as to transmit light from the LED to the vehicle while the operator is driving the vehicle. A distance sensor measures a distance between a vehicle body and an object near it. An emission control circuit controls the LED based on an output of the distance sensor, thereby indicating predetermined information, such as a distance warning to the operator. An indicating portion is disposed on an end of a corner pole or a fender marker to receive light from the LED and transmit light to the vehicle operator without requiring the vehicle operator to substantially look away from the direction the vehicle is traveling or a mirror showing the driver the vehicle'"'"'s traveling direction.
