Headlights: - Not the sort on the van, but the sort that have an elastic strap arrangement and fit on your head.

Does anyone used these? Are they any good or just a bit of a gadget that's not really all that? I was just thinking that having some sort of light with the beam that shines in the place where you're actually looking and probably trying to connect something may be a good idea?

Thanks for your comments in advance
