Another user just directed me to this thread- I like what I see! My GF's jeep is in need of some aux lighting and this might be just the ticket!
BUT, my primary concern right now is with single LED small form factor. I ready the whole thread and saw you had started design work on one but seem to have abandoned it. I can tell you this for sure- IF you built one with a diameter of 2.25" or less and reasonably priced (in the same range as vision X; $90-$120), I'd be on board for six of them! I need two for each of my two quads and two for a friend's to mount on the handle bars and toss light in the direction we are steering; the factory pod light just does not cut it.
As far as electrical engineers... I know a LOT of engineers; mostly civil, structural and mechanical, but I'll ask around; they may very well have a solid contact. Is there any sort of profit in it for whoever may be qualified? Perhaps maybe a couple free lights? I'll start asking around right now, but that info might be good to know as I'm spreading the word.
