I got one of those that staps to your head and it's pretty bright but I don't know about seeing eyes. I do have one of the ones that clip to the bill of your hat. It's got 3 leds and it comes in white,red,and green. I love this thing. Hands free to do other things. Now a gun mounted light with LED's, HMMMMMMMMMM !!!!! Just throw the consept out there and someone will come up with one with a builtin battery. Totally self contained on the gun with no wires or external batteries. :shock: :wink:
