    Hi, would someone be able to confirm which segments in the tail lights are active with the rear fog light on a euro model (France to be more specific)? On the wiring diagram that I have it shows that the inner segments of the inner tail lights are the rear fog (euro version). But looking through threads I see europeans mention that they had a full lamp on the one side only illuminate.
    Could someone with a France delivered F355 confirm which light segments come on when the rear fog light switch on the console is activated?

    Cheers

    How many bulbs do you have on the inner lights (both sides)?

    Single outer segments sometimes give the impression that the whole ring is illuminated. The light from one half bleeds through to the other side.

    It's common for European cars to have Park lights on the driver's side only (possibly for battery saving when the car is parked). However, I don't know why you would only have one fog light on one side when you could have two for better visibility and redundancy.

    I have a USA spec car, that I am modifying for European homologation. The inner lamps have 3 bulbs, so I can make any configuration that I need, but just wanting to put it in the actual configuration that French cars were delivered.
    The single fog light on the rear in Europe is quite common, I've seen hundreds of cars like this. It is typically the left (driver) side. But some have both side (as the wiring diagram suggests). You may be correct, the half segment looks like a full segment.
    As a side note, to convert the outer lamps from USA to euro, I had to purchase the bulb holders from a euro car - the USA versions do not have the socket for the center bulb which for euro cars is the turn indicator (USA version has nothing in the center of the outer lamps). To redirect the wires to the appropriate lights, I'm just making an adapter harness (AMP Superseal connectors are easy to get)

    If someone in France, with a French delivered F355 could flip the rear fog light on and tell me which light segments come on that would be greatly appreciated :)

    Thank you for saving me some more work/headache :). I was going to get to this at some point and figure out exactly what was going on.

    How were you able to buy the bulb holders without buying the entire taillight?

    I’ll take an extra set off that adapter harnesss thank you :).

    Ah, dang, it didn't realize that there was an amber lens in there, I though that it was a amber bulb with a clear lens. In fact the lenses on the outer lamps (USA models) seem to have the center tube blocked off, so no bulb can go in there at all! At least that is the case from mine (I just checked it after your note above).
    Well I do have another set of inner lamps with a clear center lens, so I can use one those on the outer with the amber bulb and see how that looks. But was hoping that this conversion would remain as simple as possible.

    Thanks for the heads-up on that, I'll make a second set of Superseal adapters for you, can give them to you next time I'm in LA.

    Hi,
    my Swiss 1996 has the rear fog light ONLY on the LHS inner pod, and in this pot the right segment. The bulp is a clear 21W, shining through red plastic. No fog light on any other of the 3 pods.

    No fog light at the front.

    Best regards, Simon

    That would indeed match (at least half) of what the wiring diagram suggests. Any idea if it was just the right side or both sides?

    Thanks Simon! That is the configuration that would make the most sense to me, thank you for the confirmation!

    Oh wow! that's odd. Was there an incorrect bulb (higher wattage)?

    Was just thinking that maybe the wiring diagram is indeed correct, that the wires do go to both the left and the right inner lamps (the inside segments), but only one bulb is installed, depending if it is LHD or RHD. I presume that the fog light on the RHD cars is the inner segment of the right hand inner lamp only ?

    The fog light being only one side, that being toward the middle of the road (ie left for LHD cars and right for RHD cars) make sense and is consistent with what I've seem on European roads.

    My RHD Australian car has 2 rear fog lights. I don’t know if that’s standard. The Owner’s Manual shows a LHD car’s right hand tail lights with a fog lamp on the inner cluster. The manual is multi language so perhaps it is universal LHD non-USA manual. Side turn repeaters are shown.

    The parts manual doesn't list foglight bulbs or bulb quantities

    To answer the left or right, some country rules are one rear fog, others allow or require two.

    You see these differences quite frequently. Even on US market cars that have rear fog lights. Some are left only, others are right and left.
