- This document specifies that black is the only color that can be used for the insulator at the bottom of the base of T-1 and T-1 ¾ Flanged Base lamps.
- Content
- This document did not address the possible increase in NVIS radiance that can diminish the pilot’s visibility when using Night Vision Goggles. This diminished visibility is caused by any color insulator with the exception to black insulators on the bottom of the base of T-1 and T-1 ¾ Flanged Base lamps. The reason for this revision is to eliminate all colored insulators with the exception of the color black, from the bottom of the base of T-1 and T-1 ¾ Flanged Base lamps.
