Will it work as drawn? Yes. Is it the most efficient design for the
job? No. Is it pretty simple and easy to build? Yes. However,
there are several single-point failure points, but if this aircraft
isn't designed for hard-IFR or if you choose to carry a backup
flashlight you should be OK.

I have cobbled together a circuit from available internet sources to
illuminate a homebuilt aircraft instrument panel. I was wondering if
those qualified in this group would mind reviewing the schematic and
making constructive commentary. I'd like this thing to be reliable and
not cause a host of other electronic gremlins. Just keep in mind, I'm a
chemist, not an electronics professional. But, I do learn quickly.


Thanks.
