An illuminated sign, readable during the night or day, and suitable for use as a house number display, uses a single illuminatable panel, on which a number of stencils are plac critical flicker frequency ed. Each stencil is a rectangular piece of opaque material, such as plastic or metal, in which a central cutout is made in the shape of a number. Several of these stencils are arrayed in front of the illuminatable panel, so that only the light coming through the central cutouts is visible through the stencils. The illuminatable panel is made of an array of LED's, with a diffuser to produce a uniform illumination, and is powered by one or more batteries. A light detector senses the onset of dusk, which activates the illuminatable panel, turning it on, and leaving it on for four or more hours. A constant-current electronic system powers the LEDs, which are pulsed on and off at a speed greater than 90 Hz, which makes the sign appear to the human eye as constantly illuminated. A timer leaves the illuminatable panel illuminated only for a few hours, in order to maximize the life of the batteries.

An openable handle generally formed as a spring-closing carbiner is provided for attachment to a manually transportable object and has elongated arms connected to the transportable object in spaced relation to each other. The handle is attached to the transportable object so as not to be separable therefrom and one end of the first arm and one end of the second arm each extend outwardly from the attached transportable object. A portion for making the handle openable is located at a site between the outwardly extending ends of the first arm and the second arm, for passage therethrough of a member from which the transportable object is to be suspended.
