Havin looked at loads of head mounted lights, i bit the bullet and got one from go outdoors. (the camping people) The idea was if i get a puncture at night i could either wear it or mount it on my helmit. To my surprise this little light is very good. Its an led jobby with various options. There is no flashing option but is more than worth a look. Either as a backup light or either mounted on your bike or lid. Im comparing it to my main front light from halfords, at 35 quid. Oh the head mounted light runs from three aaa cells. Hope this is of some help folks.
