657-1415-303F is a bi-color watertight LED panel mount indicator featuring a flat lens design with red and green LED colors. The indicator operates at 10-30 VDC without requiring a resistor, with typical light intensities of 270 mcd for red and 515 mcd for green. It is housed in polycarbonate (UL 94V-0) with a polycarbonate lens (UL 94V-7), sealed with a neoprene gasket and 11/16-27 NS threads to ensure IP67 and NEMA 4X watertight protection. The device features 6-inch wire leads with color-coded wiring (red and green for LED colors, black for common ground), operates reliably across -40°C to +85°C, and mounts through a 0.687-inch hole with a maximum panel thickness of 0.350 inches. This indicator is ideal for aircraft, military vehicles, industrial panels, EV charging stations, and wastewater treatment controls where durability and reliable visual signaling in harsh environments are essential.
