headlight recommendation for my Duster
I would have recommended the Cibie E codes, but the good real ones are getting hard to find. Do you still have some?
The Cibie headlamps went out of production in 2019. They were in production for many years, with declining volumes, and the tooling was allowed to grow decrepit. Once the maker (Valeo) could no longer squeak a plausible proportion of the lamps past conformity-of-production testing with a straight face, they discontinued them. Dribs and drabs of leftover stock show up from time to time, mostly from the last couple years, but they really skidded very badly from what they once were, and they cannot in good faith be recommended. There are also cheap and completely nasty "reproduction" (i.e., knockoff) Cibies; these aren't headlamps, they're headlite-shaped trinkets not worth a nickel.
It's sad, of course, that such a storied brand as Cibie was allowed to sputter and die—same goes for Marchal, and Carello—but the picture is much rosier in terms of the functional aspects that really matter when you're driving, because there are current-production lamps quite a lot better than most of the Cibie 7" round designs were even before they skidded.
(And yes, I still have a stash of the best of the good ones, new old stock, for fellow headlight freaks and others who hafta have 'em)
