本规范涵盖了红色和白色单独仪表灯的一般要求。这份文件经过精简。MIL-L-5057F附录A列出了MIL-L-5057F采办所需的文件，是MIL-L-5057F的强制性部分。附录A中列出的文件与MIL-L-5057F（一级文件）中直接引用的文件具有相同的状态。通过分层引用的所有其他文件可作为补充MIL-L-5057F的指南和信息。本文件的范围仅限于灯源设计。此外，在新设计中不应考虑使用红色照明，并将其纳入本文件，以支持仍使用该照明系统的现有军用飞机的要求。

This specification covers the general requirements for red and white individual instrument lights. This document has been streamlined. Appendix A to MIL-L-5057F lists those documents required for MIL-L-5057F acquisition and is a mandatory part of MIL-L-5057F. Those documents listed in Appendix A have the same status as those referenced directly in MIL-L-5057F (first tier documents). All other documents, referenced through tiering, may be used as guidance and information to supplement MIL-L-5057F. This document’s scope is limited to lamp source designs solely. Furthermore, the use of red lighting should not be considered for new design and included within this document to support requirements for existing military aircraft that still operate with this system of lighting.
