By that example, anyways.

Speaking of mounting lights under the bars, are there any generic clamps that fit Cygolite headlights but use screws instead of a knob to tighten them? If I mount mine upside-down it's likely to interfere with my handlebar bag.

I'm not sure how you mount lights upside down on a bike with a handlebar bag to begin with. Seems the bag would interfere with the lights no matter what. That said, I use Marwi clamps for my lights. It only took a little ingenuity to convert the mount for a Cygolite to Marwi clamp. This is the result (sorry I don't have a better picture)

I just leave the clamp on the bar all year long. Here's what that part of the clamp looks like.

It's fairly low profile and could easily be mounted upside down.
