The 507-3918-1433-600F is an incandescent cartridge lamp from Dialight's Series 507, designed as a yellow indicator light with a cylindrical lens for visual signaling applications. It operates at 28V with a bi-pin terminal configuration and is engineered for mounting in a 3/8" hole size, making it compatible with standard panel-mount indicator assemblies. The yellow lens provides high visibility for status indication in industrial control panels, instrumentation, and equipment dashboards. This lamp type is commonly used in legacy and modern control systems where reliable, cost-effective visual feedback is required.
