Wow. That thing looks huge!
I run a tactical flashlight on top of the helmet using a TwoFish , generally in flashing mode when I'm in traffic (with regular lights on the bars) but I switch to steady when I'm on MUP or such to allow me to point light where I need it. I also run a blinky on the back of my helmet, which I've cludged quite successfully with rubber bands. It vibrates some, but it points where I need it most of the time, I think?
