I haven't had the problem, but needing a 2nd light (or a match) to
help dig through my junk bag for spare batteries is certainly a
possibility. However, I carry mine wrapped in cellophane wrap (to
prevent shorts) making the batteries easy to find by feel. (Finding
my reading glasses so I can see what's in the bag is more of a problem
for me).

When it gets dark, I theoretically excavate the headlight out of my
junk bag, attach it to the handlebars, and ride off into the sunset. I
say theoretically because I'm a fair-weather cyclist who avoids riding
in the dark.

I've commented on this in the past. My solution was to suggest that
the frame be pre-wired for dynamo lights at the factory. The trick is
to put the holes in the frame where they do not act as stress risers.
Running wires through transition areas (head tube and seat tube) is
not easy, but it can be done.
If complexity of bicycle lighting is a problem worth solving, methinks
that standardizing on the handlebar mounting would be a big help.
Making the mount a permanent part of the handlebar would be even
better. I once sacrificed an old bent aluminum handlebar and tried to
attach various Pop-Rivet type threaded inserts for mounting lights.
Since the threads don't need to support much weight, tiny 4-40
threaded inserts could be used. It worked, but the handlebars could
not be rotated for the most comfortable position, so I gave up on that
idea. I had the same problem when I tried to attach a DIN rail

to the handlebars for accessories. It mostly worked, but the
handlebars again could not be rotated.
Assuming I can get past the wiring, drilling, and rotation problems, a
permanent mount for the light, with built in contacts for the wiring,
would go a long way to making both battery and dynamo lighting more
useful. However, it wouldn't sell. Most bicycle owners do not own a
working head or tail light, don't use either, don't ride at night, and
would be seriously offended if the added cost of my proposed wiring
and mounting system was included in the selling price of their
department store bicycle. A feature that is not used by perhaps 95%
of the potential buyers would instantly disappear in the first round
of cost cutting.
So, we're stuck with various clamp mounts, all of which slip, slide,
require rubber inserts that promptly disappear, or have self
destructing "quick release" locks. At least they perform the prime
objective, which is to not scratch the handlebar finish.

Yep. One has to get experience in such things at an early age because
learning such basics when older is difficult. At one company, I joked
that perhaps we should write the user manual in comic book format.
Instead of instant rejection, the idea was taken seriously and bounced
around upper management for months. It was eventually rejected
because of the high cost of hiring a professional illustrator (this
was before computah graphics).
