The Optronics Multifunction LED Warning Lamps, Nos. SLL15ACC2B and SLL17ACC2B, employ a solid-state, surface-mount device (SMD) design that protects their electronics against moisture, shock, and vibration. The lamps meet Class 1 and CA Title 13 requirements, as well as SAE standards J595 and J845. The lamps are available in three sizes and in single-color, dual-color, and tri-color models, offering 70 to 140 possible flash patterns. The lamps feature a thin, low-profile design of 1/2" to 3/4" thickness and a durable aluminum housing. The warning lamps come with Optronics’ one-diode lifetime warranty protection, which will replace any lamp if even one diode fails.
