I've been round this before off list with others but it might help to explain
the arrangements in Europe.
Unlike the States we last used a sealed beam headlight in the early 70's, since
then everything has separate, replaceable bulbs. Running in parallel some
immediate post and pre-war vehicles used the British pre-focus bulb.

The E2 is a mandatory marking to show type approval in the EEC and is to be

The three prongs on the back will take a standard US type connector using the
same pins for ground high beam and dip (dim). The French have long since given
up on yellow lights, theoretically for anti-dazzle but removing a large portion
of the visible spectrum is the same as a white light of lower power.
The base configurations readily available are:
British Pre-Focus (BPF) - plain tungsten bulb with twin solder blob connections
and a large rim with a small half circle cut-out to align it in the light unit,
retained by a three prong bayonet cap assembly carrying the sprung contacts.
Largely obsolete by the 70's.
P43t Halogen H4 - the current twin filament bulb with a disc base with three
large locating ears, legally 60/55W but readily available (marked for off-road
use only) in 100/80, 130/90 and 180/100W. For 24V 75/70W. Three .25" blade
connections US compatible. Spring wire retainer in lens assembly.
H1 halogen - single filament for multiple light set-ups and auxiliary lights,
small disc base with a chord removed for alignment, single .25" connection,
available from 55W (Europe legal) to 180W. Spring wire retainer in lens
assembly.
P45t asymetric - Was very popular on the continent and is, I believe what your
Hotchkiss has. !2v versions in halogen and tungsten but the latter are always
45/40W. Has a large glass bulb and stepped disc base that inserts only 1/8" or
so into the light unit and is aligned by very small pressings in the base or a
pair of small punched tags. Three .25" blade terminals that are NOT aligned
with the bulb fitted axis but always lean a bit to one side. To be found as
100/100 and 75/70 in many 60's & 70's UK mil vehicles using FV426612 immersible
headlight units, eg., Stalwart, Ferret, 432, 433, 434, Saracen, Saladin,
Scorpion, Fox, Centurion, Chieftain etc.
Readily available here in 6V but you need a "continental" to get them as the
Brit ones will dip (dim) to the wrong side ! This might be difficult as France
has, I believe, adopted a system of "dealer only" for all spares, there are no
aftermarket parts or pattern supplies as we have here.
I can email all the base drawings separately if you wish.
