An alerting apparatus includes a pair of separate first and second lights capable of providing respective illuminations that are different from one another, an electrical power supply cord connected to the first and second lights for providing a supply of electrical power to activate the lights, and a motion detector connected to the electrical power supply cord and the first and second lights for activating the first and second lights for predetermined times in response to sensing motion in a predetermined area. The first light can provide a constant white illumination, while the second light can provide a flashing red illumination. Also, an alarm can be connected to the motion detector and the electrical power supply.

An identification device comprising an IR LED contained within a housing which is adapted to be carried externally by a person or object who or which is to be identifiable in dark conditions. In cases where the device is to be used as a personnel identification beacon (PIB) the housing can carry means to enable it to have a "stick-on" capability whereby the housing can be easily attached or detached to/from the external clothing of a wearer. The IR LED can be adapted to flash and this can be in a coded sequence to enable the particular wearer to be identified.

A warning light and sign apparatus includes a handle assembly which includes a top end and a bottom end. A sign-receiving bracket assembly is supported by the top end of the handle assembly. A bracket-supported light assembly is supported by sign-receiving bracket assembly. A power supply assembly is supported by the handle assembly and is electrically connected to the bracket-supported light assembly. A sign is received by the sign-receiving bracket assembly. The sign includes a first message "stop" on a first side and includes a second message "slow" on a second side. The handle assembly can be easily rotated 180 to selectively orient either the "stop" message or the "slow" message. Removable sign-to-light fasteners connect the sign to the bracket-supported light assembly. The sign-receiving bracket assembly includes a front bracket portion and a rear bracket portion, and a bottom portion of the sign is received between the front bracket portion and the rear bracket portion. The bracket-supported light assembly includes a front bracket-supported light portion and a rear bracket-supported light portion, and a portion of the sign is received between the front bracket-supported light portion and the rear bracket-supported light portion. In addition, another light assembly may be supported by the sign. A handle extension assembly is screwed onto the bottom end of the handle assembly. The power supply assembly can include rechargeable batteries, and a recharger unit can be employed to recharge the batteries.

A display device which comprises a case in which a light source is accommodated, color changing means by which the color of light from the light source is changed to a predetermined color of illumination, a display panel that is formed of a light-transmitting material to cover the front opening of the case and which is provided with a light-shielding film in areas other than those corresponding to a display portion, and color display controller that is disposed on the display panel and which controls the color of illuminating light that issues from the light source and is transmitted through the display portion. The color display controller is composed of a plurality of thin strips that have a color different from that of illumination provided by the color changing means and which are spaced from each other. The light source is disposed behind the strips, with the color provided by the color changing means being displayed when the light issuing from the light source has passed between the strips, while a composite of the color provided by the color changing means and the color of the strips is displayed when the light issuing from the light source has been reflected from the strips.

A visual signaling device having interspersed arrays of red/amber/green LED signal lamps and a center flashing strobe lamp. A side mounted joy-stick type toggle switch on the housing is operated by the user's thumb to provide the control of the signal lamps. One position of the joy-stick button operates an on/off switch, and the other three positions each operate one of the three color arrays. A separate strobe light switch is provided adjacent the toggle switch. The housing of the signaling device is bowl-shaped and held in the palm of the user's outwardly extended hand. A strap extending around the back of the hand provides assistance. A battery pack is recharged through a standard socket for connection through a cord and utility plug to a power source.
