Claims

[Scope of Claim for Utility Model Registration] A sidelight comprising a lighting bulb in a lamp chamber constituted by a cylindrical lens, and a light-shielding plate partially provided in the circumferential direction of the lens to regulate the direction of light emitted, A ship's sidelight, characterized in that the bulb is fixedly installed so that the filament has an inclined deflection angle inward from the edge of the light shielding plate in the direction in which the filament is stretched.
