I found a head lamp, the kind that clips on the brim of a cap with a row of five LED’s. One clip was broken. Also apparently broken was the switch, I couldn’t get it to turn off. Before I popped out the battery it had three lights on, after I popped them in again it had one. It has two nickel sized pancake batteries so I can’t imagine it has much power or burn time. I should look to see if the batteries are rechargeable and I could use them in my Fitbit
