Fog lamp additional function?

I was cleaning the car today and I happened to be cleaning the headlight switch. Twisted it CCW and right side markers turned on. But I pulled on it and the foglamps turned on! As if I could "flash" the fog lamps with this feature. I didn't get to try it with the engine on (see if that worked) so I was curious why the car has this feature?

Also, while we're on fog lamps: While we were searching for a TE back in Jan, we tested other cars for sale (TE also) and some of them had rear fog lamps, but ours doesn't. Or maybe it's just the bulb, but the bulb out lamp on the cluster doesn't light up if I activate it, so I would guess it didn't have this function.

I know in Europe it's standard to have rear fogs, how about in the US for the w124 chassis?

the fog lamps are turned on when you pull the switch. its not an additional feature. mercedes could have designed the switch so that you can only pull it when you are on the headlight side of the switch and not the parking light side of the switch but they didnt.

the parking light feature (turn switch opposite to normal direction) is for when your car is parked on a narrow street and you want to alert drivers to the presence of your car. some of the older parts of european cities have very narrow streets (remember the chase scene in ronin?) , so you turn on the corresponding light and park as far on the curb as possible. the side your turn on is the side hanging over the street.
im surprised this needs explaining.

pulling the switch puts it in its "fog lights on" position. thats why they go on. its NOT a feature. releasing a cocked bow makes a sound. its not a feature. releasing a ball from your hand will make the ball drop. its not a feature. chewing a piece of food makes you salivate. its not a feature of the food.

its not a feature. its an anomaly of the switch.

and you absolutely CAN turn on your headlights with the car off. you know coz the annoying buzzer comes on.

lets stop inventing stuff thats not there.

I know fully well how the fog lights turn on (rear included). I am just baffled as to why there is this additional function that when you turn it one click to the left, and pull on it, the fog lights turn on but when you turn it more to light up the left side standing lamps, the fog lights turn off. So why just one side will the fog lights turn on?

As for the rear it looks like it's the same as with the w123, except some US versions have it too but on the w123 the US versions did not come with any, and additional wiring is needed as in the w123 to install one.

No need to smart talk here, I am just inquiring about something. You seem like you know everything, so why not explain it instead? It, meaning that "anomaly".
geez you can be thick. see that bolded part?
see my previous post where i said anomaly of the switch.

do you want me to break down the engineering specifications for the switch or something? should i tell you how hard the plastic material is, or what grade the copper is? do i have to state how many engineering mules were designed before that switch design was finally settled on? perhaps youwant the results of the durability testing? or maybe the cost of the indivudual components? or comparisons to other designs? or the reason why this was chosen vs others?

you are not a 3 year old asking "why, why, why." some things you need to know, others you dont. if you want to know, do the research yourself. im not your butler.

as for the "additional function." its not designed in. its an anomaly of the switch. maybe it makes it stronger, maybe it makes it more durable. maybe it makes it cheaper. who knows, who cares. it only needs to work as intended. you wanna find out, find out.

nuff said.

so, to get this straight, you believe that the mercedes engineers planned to have you be able to flash the foglights and only the foglights, if you had your sidemarker on. and only by turning and HOLDING the switch in the out position coz it springs back to its normal position on that side of the switch.

i can see the logic.

pocket protektor 1 vell, if ve have ze car parked on ze sidewalk, and it is voggy outside, zen ze headlights vill not provide ze adequate illuminashun. so we can have ze driver show oncoming traffic zat his car iz zere by flashing ze fog lights. (emphasis on "fog" lights for proper dramatic effect. include a waggin of finger at that point.)

pocket protektor 2 ja!!!!brilliant!!! zen ze car can still be zere tomoghow, and ze driver can still enjoy his otto mobil.

pocket proteckot 1 (excited) ja, is gut. zen, ve should design ze seat so zat it leans back so zat ze driver can sleep in ze car and warn ze oncoming traffic vith ze foglights.

pocket protektor 2 (also getting excited) ja!!! ja!! schnell!!! and ve should make sure ze seat can go all ze way back so zat ze driver can be komfortable ven he iz sleepin in ze car and warning ze oncoming traffik in ze fog about his ottomobil. i sink zis is most o sum.

pocket protektor 1 (now in a frenzy) ja, schnell. mein gott. ve can make ze controls for ze mirror in ze car so zat ze driver can turn ze mirror and not be blinded by ze traffic from behind him ven he iz sleeping. ja?

pocket protektor 2 (frenzying like crazy) directed to worker standing there looking at them wondering who is going to be sleeping in their car and warning people about thier cars presence with the foglights but only when the parking light is on schnell, schnell, do eet go, go now, do eet.
runs around arms raised, jumping and yelling "ze otto is komplete, ze otto is komplete."

pocket protektor 1. changes demeanor from frenzy to aloof and haughty. on the phone to the lead 124 engineer. ze otto is komplete. ve have added sum additional necessary safety features zat you shall not know about. price ze otto as you may. hangs up phone.

the end

dont you think that if it was intended to be a feature it would have been mentioned in the owners manual? as, get this, A FEATURE????? revolutionary thinking there i know, and it takes a while to wrap your head around once in a lifetime light bulb moments like that. but seems like thats not a huge leap in logic.

i imagine you think the car is like a video game where there are hidden features, levels and powers and so on. its not.

but, persist in your tilting at windmills. if anything, you are dogged in your determination even if you are foolish in your quest.

ooh his feelings are hurt, poor boy.

its not a feature. get it. its an unintended consequence of whatever.
you couldnt get that when more than one of us said so in very nice, very civil terms, i mentioned that i was surprised it needed explaining and here you are playing it off like i was mocking you the whole time, like i had a problem with you.

YOU WERENT LISTENING. you were busy obsessing over your new found invention, the great "feature" that mercedes had engineered in secret. think what you want of it, its not designed deliberately that way. and if that hurts your feelings then so be it.
as for my character, it doesnt like being pigeonholed by a few internet posts. it said to tell you that it says its a multi splendored multi-talented character that wishes to be judged on the merits of its whole rather than its individual parts.

oh, and it said its frequently right, especially when it comes to 124 stuff.

may your 124 ownership be long and painless. like mine.

secret agents, back to work.
