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.

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.
