Norman – 1968 – Aircraft Navigation Bulb – 25W – 28V – Halogen

Halogen aircraft navigation and indicator bulb designed for use in aviation lighting systems requiring stable, high-brightness illumination. It provides efficient light output with improved filament life and thermal performance compared to standard incandescent bulbs. The halogen gas cycle helps maintain consistent luminosity and extends service life under continuous or frequent operation in vibration-prone aircraft environments.

Application:
Aircraft navigation lighting systems, cockpit and instrument panel illumination, position lights, and general aviation 28V lighting circuits

Function:
Converts electrical energy into visible light using a tungsten-halogen cycle, providing reliable and consistent illumination for navigation, signaling, or instrument visibility in aircraft systems
