I happened to be surfing along and came across this interesting link. It appears that some of these items may work with the ARC AAA series. http://www.accessor- size.com/flashlight_accessories
I ordered the headband, flashlight friend and AAA fiber optic. I'll let you folks know how it works with my AAA.
If you have any need for a sturdy, waterproof AAA battery holder for keychain or neck chain, from very plain to "gem encrusted" please take a look at: http://az123.com/darksbane/arcacc.htm
