I presume my 2005 car came with halogen bulbs but they must have
improved how long they last.

With some of the newer cars the headlight assembly is replaced as a
module. The bulbs may last longer than the plastic, which gets frosted
by UV and road grit. They're about $50 a pop for my car, plus a few
magic moves to find all the mounts.
