2. Description of the Related Art As a light emitting means for warning at night or in a dark place, traffic control, construction sign, etc., one using a fluorescent material or a light reflecting material and one using a light bulb or a light emitting diode are known. .

Since a substance using a fluorescent substance or a light-reflecting substance emits light only when it is exposed to light, for example, even when an automobile approaches, an obstacle or a worker can be recognized until the headlight is illuminated. It may be dangerous. On the other hand, a light bulb or a light emitting diode can be recognized at a long distance because it can always emit light, but since these are point light sources, a long transparent cover is provided for easier recognition. It has been considered to incorporate one or a plurality of light sources in the body and diffuse the light substantially uniformly over the entire body (see Japanese Utility Model Laid-Open No. 4-61117).

As described above, the indicator light in which the light source is built into the long transparent cover body to disperse the light substantially evenly from the whole is used as a warning of a dangerous place, traffic control, road and building construction signs. When it is used for such purposes, it must be made in various lengths depending on its use, place of use, portability and transportation, and convenience of handling.

However, the light-transmitting cover body in which one light source is incorporated and the light-transmitting cover body in which a plurality of light sources are incorporated as disclosed in Japanese Utility Model Laid-Open No. 4-111117 are both conductive wires. Alternatively, since the required number of light sources are connected to the electrode rod is built into the translucent cover body of a predetermined length, in order to disperse the light almost evenly over the entire length of the translucent cover body of various lengths. In this case, it is necessary to prepare a large number of types of electric parts in which a light source is connected to a conductive wire or an electrode rod according to each length, or to manufacture each time according to demand.

[0006]
