FYI Front fender turn signal repeater lights

[gsxr]

A forum member recently asked about part numbers for these lights, which were only offered/required in certain countries. There are 3 variations, orange/amber and clear, with different electrical connectors. The EPC implies the 124 chassis only received orange/amber, I'm not sure if this is accurate. The clear version was used on the 129, 140, and 202 chassis. Anyway, for reference:


124-820-04-21 = Orange/Amber (wide electrical connector)
124-820-08-21 = Orange/Amber (narrow electrical connector, seems to only be used on later 124 chassis)
124-820-23-21 = Clear (wide electrical connector)

Sample photos courtesy of Google. The second photo shows the #08 amber light with narrow electrical connector.

The items are sold now so I will add to this
This is in no way intended as a dig at the seller but it does show what being NLA does
I have just looked at my old invoices, on 1 October 2016 I bought a pair of A124 820 0021
from Mercedes Benz of Oxford in the UK
These were amber lamps only, not with the harness ,and Sidler brand
The price was £5.35p ea plus our vat at 20%
I think they were NLA last time I asked which for an MOT (our inspection) part used on a lot
of models is poor
Why oh why did I not buy 2 sets !

The lenses are available separately, without the wire harness (and, presumably, bulb holder).

124-820-00-21 = Amber lens
202-820-16-21 = Clear lens

All three complete lamp assemblies appear NLA, and the clear lens too. The amber lens may still be available. I don't think the lens is usable without the cable/harness.

Its not so much a lens its a lamp unit, the amber lens and a moulded backing with the mounting
clips and fitting for the bulb and its holder
Its a push then twist baynet fitting I suppose its if a bulb blows and you break a mounting clip
taking the lamp off to change the bulb

Correct - thanks for clarifying! Yes, it's a lens assembly with plastic housing/backing, basically as shown in post #1 but without any wire.

Dave, the euro connectors are 2 prongs instead of 3. I am thinking about doing the modification and recently bought the amber lights with the cable and bulb holder. Do you think its worth it to try to convert the bulb holder into 2 prongs at the corner turn signal light? I think the wiring harness would also have to be converted. The repeater cable should be plug n play for euro cars. Maybe taping into the wires might be easier. What are your thoughts?

Good question. I never thought about where exactly these repeaters are supposed to connect to the chassis wiring. Euro front corner lights are the same 3-prong as USA. It may be easier to tap into the wires vs using the plugs.

Any forum members in Europe know how the repeaters normally connect?

So the repeater cable has a female end on the back of the plug. Basically the repeater harness goes into the corner light plug and the wiring harness goes on top of the repeater plug. Kind of like a piggy back connection.

Right, but there are 3 pins on the body harness... putting the repeated plug in between disconnects the 3rd pin. That's what I'm not understanding.

I think there is a part for the 2 pin plug. The third wire is for the parking light to stay on. My guess is that wire goes to the euro city lights in the e code headlight. So for the US cars, I think I would need to de pin the 3 prong and swap for a two prong. I guess it would make the install cleaner but then I would then have to get the ecode headlight to make it legit right? A rabbit hole of upgrades, haha. So my other question aside is how different are the beam pattern and light output of the facelifted headlights like my 95 vs the e code spec headlights? Is it even worth upgrading the headlights?

That is easier! 1994-95 facelift USA headlights are nearly identical to Euro-spec / E-code. The only difference is the USA lights lack vacuum level adjustment, and lack city lights. Beam output / pattern is basically the same (i.e., very good for a halogen reflector design).

Here is a picture of the euro plugs for the repeater. I recently bought a set of lights and plugs to hopefully retrofit my car. Unless I convert the corner lights to euro two pin socket, I am not going to be able to use these plugs. The picture shows the plugs that go into the corner lights and the back has pins that the wiring harness go into.

I finally figured out the disconnect here.

North American 124's have different front corner lamp functions vs ROW! The corner lamp in NA has TWO functions... both marker light (first position of the headlight rotary switch), and also turn signal. The bulb used is dual-filament, and the bulb holder has 3 pins.

ROW 124's are different. The corner lamp is apparently for turn signal only, with a single-filament bulb, and the holder only has 2 pins. The marker light function is handled by the T4 "city light" inside the headlight assembly. NA models do not have the city light.

I did not know this. If someone wants to add the fender repeater lights to a NA vehicle, custom wiring is required. The factory harness shown in post #12 above will not work in USA / Canada, eh.
