Different strokes for different folks, of course. My "stroke" is to use dynamo-powered lighting. The headlight is mounted on the fork crown. I can get people's attentions by wiggling my handlebars. It's a huge plus for me that I never worry about how much run time is left on my lights. Another huge plus is how smart the optics are: the light isn't super bright, but it is evenly painted on the surface, which makes it effectively more than it otherwise would be. Hot spots in lights tend to blind me, especially since I can't seem to help the fact that I focus on them. One downside is that it's not bright enough to go fast in extreme darkness. No big deal for me. I slow down a bit.
