Best flashlight to use as a bicycle headlight? Stock not modded. Preferably 18650 or 21700.

Planning on riding re-purposed rail trail with a MT07, that’s probably going to slip. Thanks for posting though.

Once the ice age ends up here I’m going to try using an aluminum go pro mount bolted to the tube of a bar extender, one of the ones that have an aluminum clamp on both sides of the stem. Then thread a metal camera stud to go pro adapter into the light. The plan is to rest the back half of the light on top of the stem with some padding and snug it down with a velcro strap.

The C8 flashlight has been copied by many companies and is popular with modders. Now they are changing the design a bit and calling it a C8.2.

Single emitter, single 18650 cell with a 40mm+ diameter head.
