I either saw it and forgot to post about it, or didn't see it previously, but Stern had a funny piece about a year ago (here) about headlamps, with a link to an old 1967 article about the poor showings of vehicles put through DC's strict periodic inspections at that time.
Nothing new under the sun/moon, I guess, only now instead of articles about how many vehicles flunk inspection (because their lights are misaimed), we have articles about how many vehicles get poor IIHS headlight ratings (because their lights are misaimed).
