Griff,
Thanks buddy.
'Marcus',
Um, wow, that's TOO kind, but thanks very much.
Having bored the nacelles entirely through I now saw a need for a reflector 'cone' that would span the entire inside diameter and lacking one I took a larger one meant for a "bulb", cut down to overal diameter and then placed atop my original one that accomodates an LED. Lines the inside of the nacellewith self adhesive detail foil and condcuted a light test.
There'll be two modes for lights- constant full intensity OR a 'flickering' effect, just for variety. Oh, of course, there's also OFF.
