Not as cheap as the last time
but still good enough for me to buy a second one.
Cree LED Hodgson Headlight
The price is $10.99 and there is a $2 coupon automatically applied.
I know there are a lot of bad reviews and it is a little wonky due to its size, weight and shape. But I've been using it everyday for months on my helmet and it's been flawless. The on/off switch has a perfect design for me and it is very, very bright. Note, I'm not using the original 18650 battery that came with it.
