I bought a Fenix BC21R bike light and have been using it as a flashlight for walking. It's pretty good, can use both walking and biking, usb charging, and the way they have an extra beam to fill in the ground between you and the main beam works better for walking than most other flashlights I've used:


I walk with it on the the mount as it provides a solid grip, but you can also take it off the mount easily.
