Looks great. No luck finding the mass-LED boards among security camera/spotlight equipment suppliers? I've seen a lot of bullet-type cams and spotlights with tons of LEDs bundled together. But now that I think about it, those may not have been smaller than 3". Just thought I'd mention it in case it helps.

 

looks good!

 

i like it!.. the gif is nice but can you upload the actual video somewhere? I really want to check it out

 

Here's a 3.5 mb vid clip...it's a MOV file so you'll need Quicktime to view it if you don't already have it (it's the format my old Nikon captures in)
It's a ccfl tube.
It's pretty easy to make, but it would probably be easier and cheapier to buy the strip and slightly mod as needed. Here's a website you can check for various shaped led modules - http://www.vehiclelight.com/

 

Man, that looks freakin' sweet! They go perfect with the led brake lights. That's a lot of work, too, for a seemingly simple turn signal mod.
