High Beam Flash Inoperable

I have an 85 300D. When I pull the turn signal lever towards me shouldn't the headlights flash on high beam? I though this was a feature on this model. Any suggestions?

This feature does work on all of our W126's and our W123 300D....but does not work on my W124 300E.....I am wondering the same thing. Should this work on ALL MB's? And if not, why?

nope the headlights aren't supposed to flash, only corners and rear turn signals, and side markers if any. it's prolly smarter that way, so you don't blow out the headlights from turning them on and off--they're more necessary to driving than the ones that blink during an emergency.

You sure? Both my friends 76 300D, another's 85 300D, and my 350SDL all have flash to pass. It is only active when the key is turned on, perhaps a contact or connection in the ignition switch has gone bad.

Yes they are supposed to work. Its the high beam flasher ( high beam available independent of exterior lamp switch position). Could be a dirty or bad combination switch.

^ Agreed, do the high beams stay on when you push the stalk forward?

Mine do on the 300E, even though the passing flash doesn't work.

My 85 300D head lights will go to high beam flash when I pull the stalk towards me, and return back to where they were before I pulled the stalk.

Hope I don`t blow out my headlights

Might be a defective switch is why they won`t flash.

I live on a dark windy mountain county road. and since the fog light only come on with low beam, I use to pull the stalk forward to high beam for more light. this is before I rewired the fogs to come on both high and low.

This is normal, the "flash" term is misleading. When you pull back on the stalk, the high beams will come on and stay on for as long as you have it pulled back. When you let go, it'll return to the neutral position, push it away, they stay on.
The fogs turn off when the high beams are on, so when you have the fogs on and pull back on the stalk, you get high beams and no fogs for as long as you make the connection with the stalk. I pull back and let go quickly, multiple times, causing a flash condition.

You are correct.
the fogs do turn off when going to high beam. BUT. when I am on low beam, and have the fogs on, the fogs will stay on when the stalk is pulled towards me and the high beams are on, which will light up the forest on our dark mountain road.

Yes the term Flash is misleading. the turn signals flash when the stalk is moved up or down to indicate a turn. and will cancel when the steering wheel is centered after making a turn.
the light on the 4 corners will also flash when the 4-way (emergency) switch is depressed.

I could be wrong, but we have been aiming this 300D between the lines since 97...........haven`t blown the headlights yet by flashing them .

That is not normal, but am glad you have no problems. I understand it's a law to not have high beams and fogs on at the same time, (as a matter of fact, you won't pass inspection, around here, anyway, so just turn the fogs on with low beam) so you shouldn't have an electrical issue, just a chat with the authorities, at worst.

I do the same thing when its really dark and rainy, I will have the low beams + fogs on, and will pull back on the stalk in my 300SD to power up the high beams, for ALL lights. Its really bright! Probably decreases lamp life though, that's two filaments on inside the bulb at once.

Don't both filaments light whenever the high beams are on?
I have not tried the SD yet, will soon.

Only when you pull back on the stalk. Pushing it forward activates the high beam filament only.

I have this problem with the 190E. Nothing happens when I pull back on the stalk, but forward activates the high beams. My guess leads to the combination switch.

Mine used to go on when I pulled the stalk, now it doesn't. Can anyone tell me how to get at the contacts?
