[Problems to be solved by the device]

 The stacked signal indicator lamp shown in FIGS. 4 and 5 has three indicator lamp units stacked vertically. However, depending on the installation location, it may be sufficient to stack two indicator light units, or it may be better to stack four indicator light units.

In the stacked type signal indicator light shown in FIG. 4 and FIG. 5, even if it is necessary to change the number of stacked stages, the number of stacked stages cannot be changed. This is because the length of the screw 22 for fixing each indicator light unit is constant. In addition, the length of the electric wire pulled out from the power supply unit 4 and extended along the cylindrical bodies 20, 11, 15 and 19 is also constant, and the number of stages cannot be changed.

In the stacked signal indicator lamps shown in FIGS. 4 and 5, each display unit has a blinking lamp of the same type. Depending on the application and installation location, for example, you may want to change the central display unit to a rotating lamp. Even in such a case, in the conventional stacked type signal indicator lamp, it is difficult to change the blinking indicator lamp located at the center into a rotary indicator lamp, for example.

The present invention has been made in order to solve the above-mentioned problems, and an object thereof is to provide a stacked type signal indicating lamp whose number of stages can be easily changed.

Another object of the present invention is to provide a laminated signal indicator lamp which can easily change an already installed indicator lamp unit having the laminated signal indicator lamp to another kind of indicator lamp unit. That is.
