The nitelite tracker from valley creek is the one i use. Quick track also makes a very nice one called prowler lights i believe. Mike can get the ones from quick track for you i believe

how do you like that tracker??? seems like it's a good option. i can't see myself trying to keep a hardhat on while running in the woods. does the hat ride well with the light on it?
the ones i'm used to are the compacts but it seems i may have to go to something more this style.
