Yes it's a cheapo Harbor Freight helmet.
Bout 4 years ago internal batteries went dead, helmet wouldn't darken. Ordered battery
holders, didn't have time to wait, bought another HF helmet. My old helmet and battery
holders sat on a shelf.
Re-discovered them last week, soldered in some wires from the holders to the board, used
rtv to mount the holders (they were made for a circuit board, they weren't flat on the
bottom). Some 2032 cells and it works like a champ.
Now that I know it works, got battery holders ordered (6 for 87 cents delivered from you
know where) for when my newer one dies.
