A stack light will typically have up to 5 differently coloured segments to indicate various conditions on the machine or process.

Stack lights are used in a variety of machines and process environments; specific colour-coding is assigned by the system designer.

Stack lights are available for all types of industrial environments including washdown (IP65) and explosion proof.

Stack lights are used in similar applications as beacon lights/strobes, however the information they typically display encompasses more machine/process conditions.

Stack lights typically use incandescent, LED or xenon-type strobes as their illumination source.

Flashing control may be provided by the stack light's internal circuitry or externally controlled with timers or logic controllers.

Later that night, Stockton collided with Slieve Bloom near South Stack Light.

It is similar in this regard to the later-released Stack Light Rifle and the Sega Menacer.

Stack Lights (commonly used in AndOn & Lean Manufacturing Initiatives)

IEC60073 addresses machine state colour-coding & acoustic alerting, which can be applied to devices including panel pilot lights & stack lights.

Stack lights are generally columnar structures in a variety of shapes, placing colour-coded indicator segments on top of one another in a "stacked" orientation.

Like the Atari XG-1 light gun, the Stack Light Rifle was treated by the hardware as a light pen.

The main component of the Stack Light Rifle System is the electronic target pistol that is connected to the computer by a generous length of lead.

Produces a large range of Signal beacons (LED and incandesent lights, strobe's and flashing versions)and tower lights (stack lights), buzzers, sirens and bells.

Stack lights are passive devices that may be controlled directly by programmable logic controllers, distributed control systems, PC control systems or hardwired to machine controls such as timers, sensors and latching relays.

Although the Stack Light Rifle or SLR combines the looks of a gun with part of the optical system of a camera it can hardly be rated as a precision piece of equipment.

Constructed from bright white stacked light consoles, the undulating cones change colour and emit light 24 hours a day - bringing a much needed sense of unity between the sparsely dotted public spaces, guestrooms and leisure areas.

The Stack Light Rifle is a light gun that was manufactured by Stack Computer Services and created for the ZX Spectrum, Commodore 64, and the Commodore VIC-20.

In conjunction with SCADA supervisory control systems and user interface/HMIs: SCADA/HMIs provide more specific machine/process status data; stack lights complement them by providing visual/audible feedback away from the machine operator console.

The Stack Light Rifle is differentiated from future light guns as being very realistic looking; future unrealistic light guns such as the NES Zapper and the Sega Light Phaser dealt with controversy due to the guns still being misidentified as real firearms.
