Abstract: A flashlight with signaling lamp suitable for miniaturization and having good operability is provided. A cylindrical slide body (20) is fitted over the outside of the upper portion of the main body (10) within which a battery is accommodated. When the slide body (20) is slid in upper and lower directions of the figure, the entirety thereof is expanded or contracted. A colorless transparent plate (24) and a reflection plate (25) are provided within an illuminating tubular portion (21). When the entirety is contracted, lamp bulb (40) is positioned within the illuminating tubular portion (21). Thus, this flashlight can be utilized as an illuminating lamp to irradiate the upper direction of the figure. In contrast, when the entirety is expanded, a scattered light by a signaling tubular portion (22) comprised of transparent plastic of red is obtained. Thus, this flashlight can be utilized as a signaling lamp. Inside the signaling tubular portion (22), a groove (22C) is dug.

Abstract: A multi-function lighting device in the nature of a miniature flashlight and which can serve as a miniature lantern or lamp, as well as a miniature flashlight, and as a miniature signaling device. The lighting device includes a housing with a head for directing light axially outwardly in the nature of a collimated beam, so that the device can function as a flashlight.

The head unit includes means mechanically coupled to the switching mechanism whereby the electrical circuit to the flashlight bulb may be switched off and on as the head unit translates along the socket/switch assembly. The switching mechanism has essentially no slack, and therefore switching occurs with only a small axial movement of the head unit.
