since. Now I'd like to add lights so I can make one
last trip in the evening with it. As-is I have to
drive to class at five in the afternoon just so I'll
have my car at 9:00 when we leave. I'd like to avoid
all that and just use my bike for that one short trip
at night.
Good plan.

on an ancient ten speed? It's a short trip, so
efficiency isn't too big a concern.
Efficiency is always a concern!
Quoted message said:You might consider a cheap generator set. I know one
person who has a <$20 generator set (from a discount
store) on her commute bike, and it's been working fine for
several years now.
Seconded.
Modern generator/dynamo sets are cheap, light, and last well
under light use (pun not accidental :-)
Quoted message said:I helped her out by replacing the stock bulb with a 2.4
watt halogen bulb, which was certainly worth it, and I double-
wired the headlight (that is, I did not rely on the bike
frame as a ground.)
In the UK a lot of people mount the dynamo at the front, and
use the its full output to drive the headlight directly (and
double wired) with a 3 W bulb.
The rear lighting is then performed by a small, cheap LED
light which would probably run for a year on a pair of AAA
cells under your planned use.
Quoted message said:The beam is much better than any comparable headlight, and
there are absolutely no battery worries. It always works.
It will slow you slightly, but not enough to worry about.
(Get used to maybe 15 mph instead of 17 mph.)
The current (again, awful pun deliberate ;-) dynamo
generation (aaaargh! ;-) also produces good light at low
speeds. My beater bike with its new dynamo system
produces full light as long as I'm moving fast enough to
stay balanced.
Quoted message said:You do need basic mechanic skills to install it and align
it, though.
And it is worth checking regularly.
