Tough keychain flashlight

[Christoph]

I have had a Klarus mi6 ti on my key ring for years it gets dropped banged around hitting the steering column and generally beat up still works every time I believe the light is potted I should have bought several however this one is still going good I think its at least 4 years old maybe more.

I'll second the Surefire Titan as a keychain light. I'm surprised by all the photos posted here of lights not on or abused as actual keychain lights.

Again, SS Peak Eiger.
Very robust, and it will run on any battery that will fit in it.

If AAA durability is what you need:
1- SureFire Titan
2- Any single-AAA model from Peak
3- Old model Fenix L0D

I haven't had an issue with my keychain light (formerly a Tube and now a Tube V2). I also own a few EO1s, EO1 V2s, and EO5s but the Tube works best for me as a keychain light. I often carry an Olight I3T as well (in my pocket).

I have a AAA rayovac that is claimed indestructible and has worked great. Uses plastic, a much better material for the pocket. Pathetic output but it works.
I also use the Folomov EDC2 and the Fenix LD02 v2 which are small lights with no key ring.
