• Mounting auxiliary lamps similar to the front position lamps is an effective means of improving the visibility of motorcycles. Among possible factors which may influence discernment of the auxiliary lamps, the authors have examined factors such as the surface area, luminous intensity and luminance of the auxiliary lamps conducting outdoor experiments. The auxiliary lamp is made up of amber-colored light emitting diodes (LED) with 32 LEDs in the horizontal direction and 16 LEDs in the vertical direction. The experiments consist of two parts, a static experiment in which the observers observed a stationary motorcycle and a dynamic experiment in which they observed a moving motorcycle. The observers were instructed to evaluate the following three items : (1) Conspicuousness of the motorcycle(2) Brightness of the auxiliary lamps(3) Appropriateness of the auxiliary lamps.Experimental results and discriminant analysis of the data show that the luminous intensity of the auxiliary lamps strongly influences how the lamps are discerned.
