Let me know what you're after, We've made a ton of custom lights, and ours have 16 different patterns in case you get bored of Knight Rider.
I was originally planning on building our light for the Vehicross, it just ended up that our housing is an absolute pain to work with (pull it off and you'll see, absolutely no room for a PCB) But if you want a light to retro fit or to put elsewhere, We have 16" lights. Plus a controller to adjust the pattern, or you can adjust jumper settings.
The Vega project was hatched because our 3BL housing sucks. And it'll be perfect for motorcycles looking for extra "attention" safety...
Pretty soon we'll be doing more and more custom work.

That's my brother's company for doing custom lighting.
