Federal Signal’s Model BPL26ST is a portable, battery-powered strobe warning light which flashes 65 times per minute. Its components are moisture-proof and reverse polarity protected to ensure extended battery life and trouble-free performance. The BPL26ST is available in five fresnel dome colors - Amber, Blue, Clear, Green and Red. For increased durability, the dome is made of Impact resistant polycarbonate and the base is constructed from a high-density polyethylene. A flexible rubber seal covers the on/off switch to protect it from the elements.
