The present invention provides a new runway-embedded flash lighting device that is light, has a long life, has high effective luminous intensity, can switch the luminous intensity, is low in power dissipation, and is excellent in heat dissipation. A runway-embedded flash lighting device (1) includes: a cylindrical body (10); a ceiling member (11); a light guide member (12); an LED flash light source (13); and a heat conducting member (17). The cylindrical body (10) can be embedded in a runway, the ceiling member (11) is placed in an upper opening of the cylindrical body (10) in a state of being able to be exposed to a runway surface when the cylindrical body (10) is embedded in the runway, the ceiling member (11) is provided with a flash emission window, the light guide member (12) is placed in the flash emission window, the LED flash light source (13) is placed inside the cylindrical body (10) in a state of capable of emitting flash toward the light guide member (12) placed in the flash emission window, the light guide member (12) allows flash emitted from the LED flash light source (13) to be emitted to an outside from the flash emission window, the heat conducting member (17) is placed inside the cylindrical body (10), a part of the heat conducting member (17) is in contact with the LED flash light source (13), and at least a part of a rest of the heat conducting member (17) is in contact with the ceiling member (11).
