Thanks Joe. Just a heads up on these lights. Once again I should have done a little more research but fortunately I have a plan B.
Back in crappy tire today and thought, maybe I'll get some spare batteries for these little lights. Almost had a heart attack when I realized it costs almost 12 bucks for 3 batteries!

..... I bought every light they had on the shelf! 9 of them! How can they sell for 4 bucks when batteries cost 3 times that!?
Anyway, no replacements, I'll be powering the lot of them from a external power source once batteries go dead thank you very much!
