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
