For any rescue activity, it’s always a good idea to carry a backup light, just in case... The e+LITE should be that light.
This truly tiny headlamp is huge in performance: it can be used in all conditions, has 2 power modes (15 and 50 lumens), red lighting option and strobe in either red or white lighting.
It has a built in whistle, and comes in a weather tight case that is not much bigger than a butane lighter! Batteries included. 26g.
