GoPro mounts. End of story.
I patrol in Fairbanks Alaska, todays sunset was at 2:58pm, last bus was 3:15, and sweep started at about 3:35 and went to 4pm.. I know darkness. I personally have a couple different lights that I can use on my helmet, all of which are much more powerful than a headlamp and all have a GoPro mounts on them simply because it's the easiest and least expensive way to mount stuff. Get a decent bike light or even a cheapo "dive" flood light from Amazon for $30 depending on what you want your beam pattern to be. Pretty much everyone makes a light with a gopro adapter available for it. I've personally found that the cheapo "dive" flood lights are perfect for working on stuff and skiing at moderate speeds, I got two of them infact, one for the wife and the other for me. I also have Light&motion Imjin 800 lumen spot that I use, wish it had a bit wider flood pattern, but the throw is pretty decent.
