Head light head ache!!!!
 

Hey everyone. To start I have an 86 325e 4dr. Headlights are set as follows. When the Low beams are on, I can run my fogs. And when i turn my high beams on the fogs turn off, Which is whatever, I dont care. THE PROBLEM!!!---> So i'm coming back from work and I turn on my headlights (lowbeams) and fogs on, to then see the driver side lowbeam is out. I get out the car and jiggle it to see if its loose but nothing. I then flick my Highbeams on, which shut off the fogs, AND MAGIC, all four lights are ON (Two lowbeams two highbeams). But when i take off my highbeams only the passenger side lowbeam stays on.
HELLLP!!!!!! Is it that my driverside lowbeam wiring for the driver side is messed? I dont see it being a fuse (i checked) and it can't be the bulb. Any suggestions or has anything similair happened to anyone?!?!

Bulb may be dual fillament, I can't fully remember

Yeah, sealed beams have dual filaments. One for high, one for low.

and the problem is that easy?!? Alright lemmi check that.

Go to crappy tire, buy a replacement light for the driver side lowbeam and all will be fixed.

+1 on dual filament

E30's shouldn't have dual filament beams that's why they had 4 head lights in the first place. 316 and 318 E21s on the other hand..... :)

Although that would be good if you wanted to do a driver side highbeam delete for a CAI... you could still maintain a high and low beam
hmmm....

Light output of a sealed beam is horrible to begin with, thats why you need a dual filiment low beam for when you switch to highs, that way you might be able to see something on the road.

Three facts:

A. sealed low beams are dual filament
B. sealed low beams are WAY better than US ellips
C. when the glass gets pitted, spending $7 on a new bulb for new glass is nice.

That is all.

I vote to skip replacing the light and get euro ellips, e30 with awesome light output FTW

Really?

Whenever I turn on my highbeams it looks like the outer lights turn off and the inner light turn on. To be honest though I've never actually gotten out to look at my lights unless my check panel tells me to lol.

In retrospect I guess that makes sense since the plug for the lowbeam has 3 wires going to it.

For real, yeah. Maybe you have different bulbs, but the 2 E30s I had with sealed beams had dual filament low beams that were actually very good compared to the US ellipsoid candles I have now.

They must not have HIDs in them...US ellipsoids with HIDs is good bang for buck lighting!

They've been dual filiment since the 60's, maybe even earlier. They're the same low beams that go on pretty much every 60's american car with round headlights (1964 Ford Galaxie 500 just for example). That's why they're a three plug... one plug for low beam power, then it switches to the other plug/filament for when the high's are on.

what about 316's? i still got the factory lights on my 316. my highbeams are retardedly strong
