PURPOSE:To facilitate the change of assembling work by composing a socket to be attached/detached in a circumferential direction for separating work processes properly, and improving the design of a multi-stage signal display lamp by lowering height per light source unit. CONSTITUTION:A chassis 51 on which a socket A having a diagonally installed bulb 1 is inserted and supported to be freely attached/detached is set as one light source unit, and plural stages of the light source units are laminated to compose a signal display lamp. The plural stages of the light source units are fixed through spacers 54, and they are enclosed by a glove 6 having transparency. The bulb 1 in each stage is lighted by a signal input, and signal light colored by the glove 6 is radiated around. |
