Terrain avoidance at night becomes a problem only in unpopulated areas
under an overcast moonless sky. It has happened, so it is a real
issue, but most pilots fly in areas where there are at least some
ground lights, moon or stars, and it is really not that hard to tell
if you are heading towards a mountain. On the other hand, unlit towers
are a real concern, regardless of whether it is day or night, and this
is why they get NOTAM'd.

The above is an excellent example of bad pre-flight planning. All one has
to do to avoid terrain, day, night, IMC, etc. is stay above the altitude
of any obstructions in the sector. As this is plainly listed on every
sectional, it is not a difficult task.
