The most recognizable difference between Euro and USA DS’s for 1966 and 1967 was in the exterior lighting. The headlights were changed to standard 7-inch USA sealed beam lights with special buckets in the front fenders. Euro cars had Halogen headlights made by either Cibie or SEV Marchal. We have photos of new cars at ports with no headlights at all, indicating that the sealed-beam lights were installed after the cars arrived in the USA. We have been told that the USA headlights were installed by Citroën personnel, before the cars were handed off to the dealers.
On USA sedans in 1966 and 1967, the rectangular Euro tail lamps made by Seima were replaced with round units made by Lucas of England. The Lucas tail lamps were standard lights used on many British cars of the era.
The Euro front turn signals (made by either Seima or Axo) were also replaced with round units made by Lucas. The front turn signal housings were chrome-plated on Pallas models and were plain aluminum on standard cars. The lens was amber-colored glass, held in position with the rubber gasket. Clear glass lenses can be found on some cars, but per the parts books, all USA cars had amber lenses.

Typical USA rear lighting as would be found on 1966-1969 cars - Lucas tail lamps (lenses held on with two Pozidriv screws), Lucas license plate lamps
Lucas lamp with twist-off lens - used for roof-mounted rear turn signals on USA and Canadian 1966 DS sedans (and maybe a few 1967’s)
USA: 1966 and perhaps some 1967
USA: 1967 to 1969
USA: 1970 to 1972
According to the parts books, the roof-mounted rear turn signals on 1966 sedans were Lucas units where the lenses were removed by twisting the lens counterclockwise. In 1967, the parts book indicates that the roof-mounted turn signal lamps changed to Lucas units similar to that used for the brake and tail lights (lenses held on with screws). While this is generally true, there seem to be exceptions where 1966’s had the later turn signal lamps and maybe even cases where 1967’s had the earlier twist-off lenses.
US and Canadian station wagons received a special rear license plate holder on the lower tailgate that was designed to fit a USA license plate. This holder was hinged such that the plate could be viewed with the tailgate open or closed. The license plate lights on the hinged panel were the same Lucas units that were used on USA sedans.

DS wagon tail lights in 1966/1967 (brake and running lights) were the same as Euro models, made by either Seima or AXO.
USA convertibles in 1966/1967 had the typical USA lighting, but lost the boomerang turn signals mounted on the rear deck. Instead turn signals were incorporated into the tail lamps using dual filament bulbs and receptacles.
The parts books suggest that Canadian DS’s in 1966/1967 had full Euro lighting. However, this is clearly in error. There are plenty of memories and photos showing 1966/1967 Canadian DS’s with the USA-style lighting. Two such examples are these period photos, one a Canadian publicity photo in Montreal and the second is the Montreal showroom. One can clearly see the USA-style Lucas tail lamps and turn signals (both front and rear).

Model year 1967 was the year that Euro DS’s received LHM hydraulic fluid. LHS2 (brake fluid) was retained until 1969 ½ on USA and Canadian cars.
DASHBOARD AND WIRING
The only substantive differences on the dashboard and wiring on USA models in 1966/1967 was that the speedometer was calibrated in MPH and the turn signal switch was different (Euro turn signal switches tended to have the flasher unit built into the switch, whereas USA cars had an external flasher unit). Cancelling the turn signal on USA switches on cars between 1966 and early 1969 was accomplished by pulling the lever aft, toward the driver.
Canadian cars had the speedometer calibrated in miles-per-hour (MPH). The parts books show that Canadian cars had the Euro turn signal switch and associated wiring, although it seems more likely that they had USA components.

Tires delivered on DS’s intended for the USA were different than tires delivered on Euro versions. For one thing, all USA sedans and wagons always had the same size tire on the front and rear: 180-380. Most of the Euro models had narrower tires in the rear.
Additionally, many USA DS’s were delivered with an unusual and nearly forgotten tire called the Michelin XH. The XH had an older tread pattern, (similar the Michelin X) instead of the asymmetric tread pattern on Michelin’s newer tire, the XAS.
There are conflicting reports whether 1966 to 1968 USA DS’s were delivered with the XAS or the XH. However, by 1969 it is clear that all DS’s in the USA received the XH.
We believe that Canadian 1966 to 1972 sedans and wagons were all delivered with 180-380 XAS tires (front and rear), however documentation is scant.
Note that the 180-380 size is also referred to in the English convention as 180-15, later called 180HR15.
