The Optronics LED Surface Mount Beacons employ a solid-state, surface-mount device (SMD) design that protects their electronics against moisture, shock, and vibration. The rugged beacon lamps are available in 5.5" and 7" heights and feature 30 selectable flash pattern modes. They come complete with 9', 12V power plug and switches. The beacon lamps meet Class 1 and CA Title 13 requirements, along with Society of Automotive Engineers (SAE) standards: SAE J595 and SAE J845. They have an IP65 rating for dust and water resistance. They come with Optronics’ one-diode lifetime warranty protection, which will replace any lamp if even one diode fails.
