A couple of things…
As I already said, the only time I actually use my headlamp, is for getting out of dark or unfamiliar woods or off big water.
For fly changing, I use a hat brim light that is maybe 5 or 10 lumens. I also never use a red light because it is another press on the button and I never felt the need.
10 or so lumens doesn’t screw up my night vison for more than a few seconds and fish ignore it.
That being said, I wear a ball cap. My go-to headlamp (currently a Black Diamond Spot) is narrow for a reason. When I need it and need to look down, I tip my cap back; put the headlamp around my head BELOW the hat brim and pivot the headlamp down.
When I want to see just straight ahead, I put it around the cap over the brim. A narrow headlamp makes this whole lot easier than some of the wider headlamp options out there.
A couple of things about on clip-on hat brim lights:
If you use a chest box, chest pack or even regular fly boxes in a vest, you will find it a royal pain in the *** to get light down into your chest box or fly box without pointing your head way down or pulling your hat brim down.
What I did a LONG time ago because I use a Richardson Box is fabricate a different mount for a Princeton Tec Impulse that attaches to my hat brim. My mount allows me to pivot the light more than 180 degrees and extend it so I can shine light down INTO my chest box, a fly box or anywhere I need light.
In my case, I couldn't find what I wanted so I had to “invent it.”
If you’re not that clever, take a look at the
Princeton Tec Point MPLS. The “Point” can attach to a hat brim (and a lot of other places) and has a gooseneck.
BTW – There is a cheaper version out there that just comes with the hat brim clip.
Another thing about hat brim lights, think SMALL because you may have an issue if you use a clip-on magnifier also attached to your hat brim. In my case, I have a magnifier & flip down sunglasses attached to my hat which is why I invented my own mount.
Finally, all of the cute small headlamps or hat brim lights made by the big three (Petzl, Princeton Tec & Black Diamond) go away in time so if you find one that is PERFECT…
…buy a few spares!!
