I came across this flashlight holster that has a reflector built into it. The design holds the flashlight like an easel and reflects the light in a broader beam. I could see all kinds of UL devices like this using a headlamp or a microlight. Perhaps a little aluminum from a windscreen or a pot lid or a strip of translucent plastic to go in an arc in front of a headlamp to soften and diffuse the light– a headlamp-shade?
