LT1 Series — SignaLight™ Light Towers
Display Lights with a Tower of Advantages
Key features of the LT1 series SignaLight towers include:
• Custom configurations meet your specifications — simply
•Select your flash preference, lens colors, number of tiers, mounting
style, and voltage
• Choice of LED or incandescent lamps
LED lamps provide over 100,000 hours of service life and are
interchangeable with incandescent bulbs
Incandescent lamps (available up to 10 watts) are vibration-
resistant and provide a 2,000 hour service life
• Replace the bulbs independently; no need to disassemble the
entire unit
• Heat- and shock-resistant polycarbonate lenses
• Flashing models allow each lamp to be flashed or steady
• Choice of metallic base or cost-saving plastic base
• Color-coded wires make assembly and wiring easy
• Mounting options include base and pole mount
