Yup. "things" happen and once in a while I find myself hiking well past sundown, usually on crummy trails. A legit navigating light is worth its weight in platinum for those times. Fact is LED technology has made carrying a nice head torch painless. Predawn summiters once toted mining lights powered by lantern batteries or 4x D cells (or carbide lamps). We're lucky as can be.

Cheers,
