Quick Lite penlights from Prestige Medical have replaceable batteries. Available in various colors.
These pen lights work great! Nothing bad to say about them.
This is a great pen light for those ""so needed"" times! And it has a safety-cap so it does not get accidentially turned on, and run down the batteries. It also allows for refills of batteries. So I am hoping to get much use out of this one penlight before having to re-order!
