My wife’s headlamp quit working so I took a look at it and discovered that the + side of the battery is not making contact with the driver. By rolling up a copper wire to make a disk and positioning it where the 2 copper bars are and installing the battery I can make it work.
When I look down the tube of the headlamp with the battery out I can see the driver with potting and 2 copper bars where the button on the battery would go.
So my question is, did something like a button fall out of this thing, could someone with the same headlamp look down the tube and see if there are 2 copper bars?
Thanks
