Not clip-on lights, but I use the AXA Nox 12S. Bolts directly into my front fork and takes two rechargeable AA’s. No bopping up or down while riding, just stays firmly in place.

It’s a good light for being seen, but won’t really light up a path for you unless it’s pitch black. I have a secondary handlebar-mounted torch that I carry in my bag, just for times where I want an increased viewing distance
