You’re looking for daytime lights to run 10 hours per charge, is that correct?

I’d say that 100 lumens is a good starting point power-wise for daylight marker lights, and of course many would argue more is better, which I don’t dispute. I will say, though, that I’m more focused on having the brightness out back rather than in front, since I’m pretty good at anticipating forward situations and— knock on wood— avoiding such collisions. I like some eye-catching action up front, but it just does not seem as mission critical as a taillamp.

There are tons of headlamp options, especially if one is not aesthetically demanding, so I won’t get into those, but a seat bag clip mount light is probably more challenging, since it seems most are designed for seatpost mounting. One which comes to mind and which I use myself is the Specialized Stix Elite 2, which’ll bang 100 lumens for 10hrs in Power Flash mode and costs $40. It’s really trim and light, too, so I think it’s a good candidate for bag mounting; so many folks run heavy lights which droop on the bag at ineffective— and unattractive— angles, reducing visibility to drivers.
