PROBLEM TO BE SOLVED: To provide a sight line guide light capable of securing high visibility and making a maintenance cost inexpensive even in the intermediate part of a long tunnel or the like while an advantage capable of making inexpensive a material cost and an execution cost having a system for providing an emitter on the wall face of the tunnel or the like is vivified by lessening power consumption and using the emitter having high luminance. SOLUTION: A sight line guide light body 31 is constituted to arrange a plurality of emission diodes 32 at a substantially regular interval horizontally. The sight line guide light body 31 is mounted on an attaching member 34 for attaching so that the light axis L of the emission diode 32 arranged on the sight line guide light body 31 is horizontal, and at an angle of 0-20 deg. to the wall face of a tunnel or the like. |
