The display surface portion 2 is provided with a first light emitting portion 3 arranged along an contour of the graphic symbol A, and a second light emitting portion 4 patterning the letters B corresponding to the graphic symbol A, and the sign marker 1 comprises an operation control portion for causing the first light emitting portion 3 and the second emitting portion 4 to emit light alternately. Whereby, the graphic symbol A related to the traffic sign and the letters B corresponding to the graphic symbol A are displayed alternately, so that it can be recognized accurately and immediately whether or not the sign is a traffic sign and what are the caution contents intended by the traffic sign, and then the sign can be visible clearly at an angle.
