No, automotive lamps (bulbs) are often rated 14V.  It's a 25 watt
halogen (and in my experience can overheat/distort the
crystal-looking diffusing lens of the fixture as well as drawing
close to two amps).  Suggest you replace with fluorescent fixture
like late Vanagons or LED fixture.

It is correct.  But they're expensive, so be sure the lamp you have
is actually burnt out.  Rated life of the original is 200 hours
according to the web. Remember it's a halogen so if you touch it to
your skin you have to wash it with alcohol afterwards or risk early failure.
