Does anybody know of a place to properly dispose of old flashlights? I have seveal 2 123A LED lights that I just have no more use for, but can't give away to non-flashaholics because they run on expensive cells and are not as bright as the MagLEDs. They really are not good mod hosts as one is a very dim titanium? X5, a Goldston (don't have rechargables to feed it), and an first generation Inova XO. What do you guys do with old lights that you don't use anymore?
