Wheres Jj ? I know she does her runs in the early morning off road and with the Alpkit. (and that comes with a flashy red on the rear)
do you need a long cable running between them?
No, the battery pack sits at the back of the head and has a built in red light which can be on on/off/flashing, the headband is very comfy and supoortive and the wire from the battery to the front torch is clipped to the side straps (theres also a strap front to back which some do/don't like, i don't mind), but i have about the same amount of hair as this little chap

. I usually wear a buff when using the headtorch, for extra comfort.
