I have now seen the Mini Morimoto in a retro, and they look amazing. I was blown away, especially considering their size. They are tiny, bi-xenon, and could fit into almost any application.
If I had to do it over again, I would use these instead of the TSX's. They are small enough I might even run quad projectors, since they are bi-xenon. That would be badass. You might even be able to squeeze them into the DRL's with a little modification.....

i finally took one of those bmw headlights apart and i don't think i'm going to be able to retro them into my depos. they are the bi-xenon projectors and look to be a little too long to fit.
these are the ones.
