Federal Signal’s 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.

LED light output coordinates with the module’s impact-resistant polycarbonate lensing. LED lamps consume less power, operate at a lower temperature, and are remarkably resistant to vibration, which makes them perfect for use in heavyduty, high vibration applications.

An optional Sound Module (Model LSH on page 46 and 47) can be added to the top of the Litestak column to create a dual purpose audible/visual status indicating signal. 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 LSB unit only but can be purchased separately for 24VDC models. The Litestak base unit can be either surface mount or 3/4-inch NPT pipe mount. All Litestak models should be mounted base down.
