One problem I have testing during the night is doing startups. There are hot-keys for instruments (CTRL I toggles all interior light stations in a flight ready mode) however the lighting panel located by the left hip is near impossible to see.
A SimHQ post pointed me at something unrelated (ground fire acoustic acquisition system) and something I'd heard mentioned before in passing but didn't twig. The mic mounted lip light.
|Lip light - 3 bright green LEDs|
Activated by a capacitor switch with the upper lip or tongue on the back of the unit.
Writing this blog entry took longer than the implementation. Here's some pics to illustrate my guesstimation of cone angle and colour (I'm told my first colour was too blue-green so here's a more yellow-green that matches the above photo better). The yellow-green mixes with the existing instrument lighting to produce another green. Still a long way off from making "purest green" (Blackadder ref.).
|Where are my keys?|
|With instrument lights, two shades of green|
|Lighting panel, left hip|
So that's lip lights added. Next.
