And cue sheets. Can't read a cue sheet with a low mounted dyno lamp (or any non-head-mounted light). That's why in addition to my dyno lighting I have a Princeton Tec Quad (3x AAA) LED lamp on my helmet. Great for night time repairs, reading cue sheets, spotting street signs, and blinding your ride partners when you forget to turn it off and you look over at them to say something. X-P
