Bikes: Some bikes. Hell, they're all the same, ain't they?
I traded pulls with a random rider a couple nights ago, and I had the light set to Low (no need for High or strobing on a dark, quiet park road) and angled down just a bit. I asked if it was too bright, and she said it was fine.
I was pretty much stuck with angling it down, though, because the seatbag would block most of the light from level and above. I went ahead and flipped the taillight so that it's now mounted upside-down, and I can now aim it straight back if I want.
Although, now that I'm thinking about it... maybe it's not such a bad idea to have the seatbag in the way, at least partially. The light would still get good distance around driver's-eye-level, but when they got closer or had to sit near me in traffic, they wouldn't suffer the direct hit anymore.
