PROBLEM TO BE SOLVED: To provide a pressure-resistant and explosion-proof light-guided indication lamp so as to reduce its size and improve its design. SOLUTION: This indication lamp comprises an indication lamp body 100 containing a light source, 150 and a display panel board representing a display pattern. Light from the light source 150 can be introduced from an opening part 121 provided in the bottom surface of the indication lamp body 100 into the inside of the display panel board installed in the lower section of the indication lamp body 100. In this way, a pressure-resistant and explosion-proof light- guided indication lamp A represents a display pattern. The opening part 121 of the indication lamp body 100 is blocked up with a translucent plate 123 capable of transmitting light to thereby construct the indication lamp body 100. |
