Does anyone know of a headlamp or similar with a remote switch? Similar to the ones that are rail mounted and have a switch near the trigger, but designed to be mounted on a head lamp?
Well... thats an interesting question! I haven't heard of anything quite to that description, wired or otherwise...
But you could consider one the of the flashlights with a remote switch (like this: http://www.amazon.com/CISNO-Tactica...4174&sr=1-6&keywords=flashlight+remote+switch) combined with a Fenix headband that holds any flashlight (like this one: http://www.amazon.com/Fenix-Flashlight-Headband-18-22mm-Diameter/dp/B001NZO85O) One easy to see downside is finding a way to run the cord from the gun up to the light, and then you are tethered to your weapon... I don't know if there is a wireless remote switch on the market, but that feels like there would be more and more to potentially go wrong (batteries, remote pointing the in wrong direction, etc)
I looked at a few headband mount systems, but those are considerably heavier.
For backpacking I use a Ptec Byte. Two AA batteries and about the lightest head lamp I could find. Going to have to go a little heavier with a switch, but prefer to keep it as light as possible.
Not planning to tether to the weapon.
