The 004-2900-200 is an incandescent panel mount indicator cap designed for use with the 004 series light shield indicators featuring a 15/32" mounting hole. This cap is manufactured from black nickel plated brass and is supplied without a lens, allowing for direct lamp visibility. It is compatible with T-1 3/4 midget flange base incandescent lamps and operates across a voltage range of 1.35 to 28 volts. The no-lens design provides a clean, unobstructed appearance while maintaining the durability of the black nickel plated brass construction. This configuration is ideal for applications requiring a simple, cost-effective indicator solution without color filtering or light diffusion.
