You could make one out of a transparent material for the shaped beam light. Kind of a statement, to say while its unnecessary I still can, but I’m also motivated enough to still cover it all with my hand.

No, the whole point is to get a light that doesn’t need a custom hood. (Actually the problem I personally have with shaped beam lights is that I would still cover it for incoming traffic to model that behavior, so it wouldn’t actually make riding any less attentive. I already own a Supernova light that is both beautiful and has a nice shaped beam, but I use a nightrider day-to-day.)
