I tried the head lights and did not find them comfortable. Plus, never really shone in the right places.
Finally found a similar solution one day in the hardware store, when I wasn't even looking for it ......... a neck light!
CT7105 Rechargeable LED Neck Light - CATŪ LIGHTS (catlights.com)
You can get this one in both re-chargeable and battery operated. I tried the battery one, but they drained very quickly. However, it had worked long enough to prove to me that it was what I wanted. So returned it and got the re-chargeable. The two lights are controlled independently, have dimmers and pivot/swivel to help you get it to the right position.
Have used it for several years now for hand sewing and sometimes too, even at the sewing machine when I need a little more light.
