Annunciator Box
The shared backlit annunciator module used across the Cessna 172SP cockpit — master caution/warning lights on the MIP sub-panel, with project-specific legends and dimensions.
Overview
The annunciator box is a shared module: a small backlit, laser-engraved indicator used wherever this cockpit needs an illuminated caution/warning legend. Rather than documenting the build on every panel that uses one, this page covers the Cessna 172SP-specific legends, dimensions, and counts — the general build technique is covered separately.
For the general build process — CAD design, 3D-printed housing, laser-engraved face plate, light diffuser, and LED wiring — see Building a Backlit Annunciator Box. This page covers only the Cessna 172SP-specific legends, dimensions, and usage.
