The 137-8536-09-201 is a sub-miniature panel indicator from Dialight's Series 137 designed for compact status indication in electronic equipment. It features a neon midget flange lamp (C7A, NE-2D type) with a mid-flange base terminal configuration and solder-type connections for direct PCB mounting. The indicator is housed in a black nickel-finished stovepipe plastic cap with brass hardware, and requires a 15/32" mounting hole for panel installation. With no built-in resistor, this indicator is suitable for applications requiring simple, reliable visual status feedback in space-constrained environments such as control panels, instrumentation, and industrial equipment.
