Definition
A general term used in the Pilot's Handbook of Aeronautical Knowledge to describe modern aircraft lighting systems that have replaced or are replacing traditional incandescent bulbs, primarily LED (light-emitting diode) and HID (high-intensity discharge) lights. These systems are used for position lights, anti-collision lights, landing lights, taxi lights, and cockpit/instrument lighting, and they offer longer service life, lower power consumption, greater brightness, and improved reliability compared with older filament-based lamps.
Plain English
Newer types of aircraft lights — mostly LEDs — that have replaced the old-style bulbs. They last longer, use less power, and shine brighter.
Context Anchor
Seen in discussions of airport lighting, night flying, runway and taxiway identification, and airport safety equipment.
Why Pilots Care
These lights improve visibility to other aircraft, reduce electrical load on the aircraft’s power system, and require far less maintenance than traditional bulbs.
Intuition Check
Do not treat New Lighting Technologies as one specific light or switch. In this context, it is a broad category of newer lighting systems and equipment used to improve visibility and safety.
Example Sentence 1
The new lighting technologies on the aircraft, including LED position and anti-collision lights, draw far less current than the incandescent units they replaced.
Example Sentence 2
Many newer aircraft now use LED navigation lights that remain bright even after hundreds of hours of operation.
