Overview
The Federal Signal LSL-024B is a blue incandescent light module for the Litestak modular indicator system. The LSL-024B is available in multiple colors and may be stacked up to five light modules to create customized machine status indicators. This 24VDC module delivers 360° visual signaling for process and machinery status indication in manufacturing, assembly line, and control panel applications.
Key Features
- 360° visual signaling with Litestak lensing design
- Impact-resistant polycarbonate lens halves that snap apart for easy maintenance and color interchangeability
- Individual modules may be set to flash or burn steadily; flasher sold separately for 24VDC models
- Blue color for distinct machine status communication
- UL and cUL listed, CSA certified for North American industrial environments
- Modular design allows quick color reconfiguration without replacing the entire stack
Technical Specifications
- Input Voltage: 24VDC
- Lamp Type: Incandescent
- Module Color: Blue
- Lens Material: Impact-resistant polycarbonate
- Mounting: 3/4-inch NPT pipe mount or surface mount via LSB base
- Viewing Angle: 360°

Typical Applications
Ideal applications include assembly lines, instrument panels, and workcells where machine status must be communicated across the production floor. Multiple lens colors communicate machine shutdown, shortage of materials, supervisor attention, and other operational states. The LSL-024B blue module is commonly used to indicate normal operation, ready status, or other user-defined conditions within a multi-color stack indicator.
