This SAE Aerospace Recommended Practice (ARP) covers the general requirements and test procedures for illuminating systems for integrally lighted aircraft instruments in order to provide (a) uniformity of illumination within each instrument, (b) legibility of instrument presentation under daylight or integral light, and (c) uniformity of illumination between instrument displays. This ARP has been determined to be noncurrent because no new aircraft use red incandescent instrument lighting. While there are many older aircraft that still use them, with a noncurrency status, the document is still an available reference for older aircraft.
