That example has no application here. I can think of many examples of "less is more" as a good thing, but this isn't one of them.

Anyway, just as a greater distance helps (cars close the gap in a remarkably short time, if you remember), so does getting noticed among the dozens of other bright lights on a busy street. Car taillights, as long as they're not broken, are always brighter than most bicycle blinkies. If you want to compete with those, and be noticed because you're unusual and more likely to be overlooked, you're going to need something at least as bright. As neat as the Superflash is, it's still not enough.

I know, and that's why I nudge it downward & switch it to its low setting when I know someone's behind me. That's the nice thing about the O-ring attachment -- it's secure enough to stay put, but not locked into place so much that you can't adjust it on the fly.
