I have 3 of these light, you can also find them at dollar stores now.
Some people mount them on their RV's. I was thinking of mounting one on my van. I think it would be an extra level of security to have a light come on when you came up to the van.
I harvest the 18650's from old laptops and drills that don't work anymore, test for bad cells and reuse these cells.
