Ok, I know it's a weird question. I'm a runner (occasional mountain biker) that runs a lot in the dark, especially in the winter, and I've always had problems seeing where I'm going. I'm good with the cars-see-me thing; got lots of blinkies and reflectors for a nice 360 degree warning, but the Tikka XP headlamp that I'm using (1 watt, runs on AAA batteries) simply just doesn't do a good enough job when running fast.
I asked this question last year, but technology wasn't quite up to snuff without giving me something big, heavy, and most importantly, at risk of overheating or melting my backpack. I've seen new bike lamps out there that look incredibly small, and may be mountable on a backpack loop or possibly belt loop.
Any suggestions? I run at about 8-10 miles per hour, so I don't need a ton of range, but definitely more than AAAs can power. I carry a backpack, but ideally, it would be small enough that I could clip the battery pack onto my body. Obviously, don't want it to overheat.
Might be impossible, but just wondering if you folks have tried any nice stuff. Money is NOT an issue here (short of a fully custom-set - I want off the shelf.)
