P7 D-bin compatible collimator and optics?

I'm wanting to pull together something similar to what Litemania made in his "Kentro" light:

Of course litemania has gone awol. :( I'm still relatively new at all of this. I have a pair of 2.75 inch holes in my motorcycle fairing that I was wanting to replace with LED lamps. I already bought the buck driver I'll need to power them off of 12V, and have the relays ready to go. I'm shopping around trying to find the P7's in D-bin rather than C-bin.

I also bought (probably uselessly so) the right size aspheric and euro-style aspheric lenses, and a pair of aluminum reflectors that, if I wanted to use them, I believe I might have to bore out to fit the P7 (they came from DX). These don't fit in with the design used in those Kentro lights though - in fact he simply uses a filter to diffuse the light, and I'm not sure where to find that type of compatible filter either.

My main concern is the collimator. I'm finding ones for P7 "optics" and beam width in degrees, but it says nothing about collimator, reflector, lens type, what the optics are made of, etc, etc, etc:

This same site also has collimators for all kinds of LEDs, but nothing for the P7:

I'm not hung up on shopping that one particular site - it's just the one that had multiple collimators to even look at.

Someone want to set me straight? I believe a collimator and filter would probably be the better choice, but I could just use my reflctors and euro-aspherics (making sure to put in a cutoff so as not to blind my fellow drivers), but my concern is that those aspherics would make the light flood even worse than they would otherwise, and that I really want the collimator to focus the light and then filter it for more gentle dispersion.

Sound about right?
