Federal Signal's Litestak status indicators are a vertical column of lights that indicate the status of a machine's operating process in a full 360º radius.

The Litestak Model LSLD modular indicator light system allows the user to combine up to five interchangeable lamp units with a base power unit. Modules are sold separately for a truly customized indicator.

Light modules come complete with a 100,000–hour L.E.D. lamp; L.E.D. light output coordinates with the module's impact–resistant polycarbonate lensing. L.E.D. bulbs consume less power, operate at a lower temperature, and are remarkably resistant to vibration – which makes them perfect for use in heavy–duty, high–vibration applications.

L.E.D. lamps are available in five colors – amber, blue, clear, green or red. The standard double–contact bayonet base retrofits into any Federal Signal Litestak unit to replace original incandescent lamps.

An optional Sound Module (Models LSS or LSH) can be added to the top of the Litestak column to create a dual purpose audible/visual status indicating signal. The LSS sound module allows the user to select from 32 tones via a simple dip switch panel. In applications where a single loud tone is all that is necessary, the LSH piezo–electric horn is a perfect audible addition.

Litestak is a versatile system that allows the user to select either steady burn or flash. A flasher is included on the 120VAC unit only but can be purchased separately for 24VDC models. The Litestak base unit can be either surface mount, or 3/4" pipe mount.
