Tape a glowstick on the side of your scroll reader.
Drop a few mini-glowsticks inside your scroll reader.
Momentary-on your high power head lamp (assumes you have one, obviously)
Strap a "regular" led headlamp to your forearm, or over your helmet down the the chin.
Google "led finger lights", you can pick them up for about $2 and they, well, strap to your finger.
Adapt a led night reader/bookmark thingy.
It's all only needed for the non-racing transits, so don't stress too much. :)
