The Norman Lamps NLI-7512-24 is an incandescent aircraft reflector navigation bulb engineered for 28-volt DC electrical systems commonly found in general aviation, business, and turboprop aircraft. Operating at 28V and 28W with a 1.0-amp current draw, this GG-10 shape bulb delivers reliable, consistent illumination from its wingtip or navigation light position during all phases of flight. The reflector design concentrates the light output into a broad flood beam pattern, maximizing visibility from the required positional angles mandated by aviation regulations.

This incandescent navigation bulb is built to meet the demanding requirements of MS25309 Military Specification, ensuring it conforms to the exact dimensional, photometric, and durability standards required for airborne navigation lighting. It holds FAA Production Approval (FAA-PMA) certification, confirming it is manufactured and quality-controlled in accordance with FAA CFR 21.303 and is an approved replacement for aircraft on the FAA-approved parts list.

The NLI-7512-24 uses a single contact bayonet (BAY15S) indexing base, which provides a keyed, secure fit that prevents incorrect installation and ensures consistent light center alignment within the lamp housing. With a rated average life of 300 hours, this incandescent bulb is a proven, widely used standard across a broad range of aircraft platforms. It directly replaces the MS25309-7512-24 military spec lamp and is cross-referenced to numerous OEM and aftermarket part numbers used in Whelen and Grimes navigation light assemblies, as well as airframes including Cessna Citation series, King Air, Bell 206, Hawker Beechcraft, and Pilatus PC-12. Sold individually as a single unit.
