As for mounting the light on your head, it's an advantage. It's not just to get the attention of drivers but it also helps you see into corners and avoid obstacles. Some cars are now coming with lights that track the corner rather then just shine off in a straight line.
Yeah, I guess it would be alright as long as the light had some type of breakaway mounting. Zip ties etc should be avoided. On my bike I find that a wide-angle headlight mounted to the handlebar stem works effectively. But then, I don't wear a helmet, and feel that something like a head torch would be annoying.
