I used a headlamp for a while. It’s definitely a big help if your shop lighting is bad or if your head always seems to be in the way of the light. However, a headlamp also has problems. It forces you to hold your head where the light shines best and your neck gets stiff.
A way better solution, in my opinion, is a clamp-on LED desk lamp with a gooseneck. You can get them for $20 at Lowes.
