Headlights flickering and turning off

[MkVme]

Hopefully someone might have a suggestion. Ive been to the dealer and they say everything is connected fine and functional and that no codes are being thrown.

However when driving, of I hit a bump or make a hard turn my head lights will flicker on and off. I've looked and can't find anything wrong. No idea what's causing it. It's almost like something is getting briefly disconnected.

If anyone has an idea of what I can check or what the problem might be it would be much appreciated.

Check the housing, and the wire harness. Something isn't seated probably, or your have a loose connector, or decaying/shorting wire somewhere. Just pull out the headlights, which is simple really, and check all connections. It might be inside the housing itself... is it one or both headlights that do this? Maybe a loose bulb?

Both lights. Everything is tight from what I can tell. I'll try pulling it all out this weekend. From what I can see without taking it all apart it's all connected. Dealer said a couple screws were loose but didn't find anything else.

Your bulb might be on it's last leg.

I am pretty sure its going to be the ignitor not making contact with the bulb.

Both lights? Take the bulbs out and check them, and try to clean the contacts up a little. Maybe even replace them. See if your issue is remedied then.

Be gentle with the bulbs when inspecting/cleaning/replacing.

Thanks for the input. Does anyone know where I can get a igniter on the cheap should that be the issue

Ebay. Don't know exactly who is good. Phillips D2S bulbs. If you want the same brightness get 4300 Kelvin.

Anyone know if this one will work?

ebay mercedes igniter

All the specs written on it look just the same as the one in my car, just different color and brand name.

heres the one in my car now , if you look on the pictures all the specs are the same

Maybe, but BOTH headlights are flickering, together? Are they both doing it at the same time? In other words, are both flickering "on and off" in unison? What are the odds of it being both bulbs, both sockets, both ballasts, or the wiring to each headlight or ballast? If that's what's really happening it has to be a common electrical feed, and the only thing I can think of is the fuse box, the headlight switch or a relay. Maybe even a fuse or the fuse box. Someone here who is familiar with exactly how they're wired will need to comment.

Its hard to tell sometimes if both have gone out. I think normally, its the drivers side. But then sometimes ( like last night for example ) i was coming home and hit a bump and my headlights went completely out for a few seconds until the came back on. No CEL or lights on the dash.

I agree with what you're thinking about the wires or fuse. There's def some sort of electrical feed being cut off. Im going to dig around a little after work and put my other set of bulbs in (OEM) and see if I can find anything. I cringe every time i see those lights flicker

Ah so you have aftermarket bulbs currently in? Suspecting the bulbs even more now. A fuse wouldn't be intermittent like that, but a wire, or lead would if it's loose in the connector port housing. I originally suggested removing the headlights and tracing the wires back. Not necessarily de-pinning everything, but just inspecting the connectors to make sure they're clean and not caked up with mud or dirt, or aren't burned up.

Now that you say you have aftermarket bulbs, there's a strong possibility they're cheap-o crap and might've begun to shake apart due to general driving.

Well, ill start with the bulbs and if that doesnt work ill start removing the headlights this weekend and see if i can find something. hopefully its just the bulbs
