RE: Sigma at Bike Nashbar
I just found they have a night light attachment (clamps to handlebar next to the computer) for only $9.00
See:

I haven't seen this in person, but I'm wondering how difficult it would be to replace whatever bulb there is with an LED and power it off the bike's system instead of the battery that comes with it (with a 15 hr life)
