E30 (1982 - 1993)
God's Chariot. The E30 was produced primarily from 1982 through 1991. The cabriolet was the one exception which was produced through 1993.

Tiny bulbs in back - turn signal, back-up lights

My two E30s were made days apart. Yet there's a different setup in the rear light panels. Not a big issue, but it's curious. My first car has a smallish OSRAM bulb in a receptacle that is the size of the larger more common bulbs. I've had chronic turn signal problems in this car. Seems every 6 months I get the dreaded rapid blink and it's always the back that's dark. Usually if I jiggle it some it'll work again. I guess I could have investigated this sooner, oh well, a few days ago I went looking for a couple of the smaller bulbs and couldn't find them at O'Reillys or Autozone.

Amazon, etc. has them but they're $6 - $8. The larger ones cost less. I had tried earlier to get the receptacle thingy out but they resisted. You would think they would come out just like a bulb but I couldn't get it. Today I gave it the power steering by armstrong treatment and got one out. Put in a used bulb that somehow came home with me from Pick n Pull and it works fine. I've never seen the small bulbs at a boneyard.

So I really don't have a problem at this point but it's still a curiosity. I wonder why this usage arose. Some advantage to the smaller bulbs perhaps? The small bulb is 20 watts and the big ones 21 FWIW.

The one on the left is QH and the one on the right conventional. The QH is used in the reading lights of a E23 among other places. Stick to the correct globe in the correct position.

Not following QH vs. conventional. The bracket thingy is identical in each. The smaller bulbs wouldn't work without the adapter jack that they are plugged into. I've had turn signal issues so often in the rear, I'm wondering if the fact of a 'middleman' sort of connector is part of it. I put a larger bulb into the jack once I got the adapter jack out and it plugged into the car and worked just fine. Whereas I was having no luck getting the smaller bulb working again. It had been working after jiggling it a few days prior, this after it had quit again, so I looked at it in more detail and my messing with it apparently sent the jack adapter too far south to work again. Whereas the larger bulb by itself did.

The whole thing is weird, the larger bulb is the one listed at the auto parts store as the one needed for that spot. Plus the smaller bulb is hard to find, aside from mail order.

The flasher unit expects to 'see' two 21w globes. That (IIRC) is a 10w. That = no function. Appears some 'auto expert' has fitted the wrong globe to one side, just because it fits. Get the correct one and that should fix the problems.

That is the odd thing about it. The bulb wouldn't fit without that adapter thingy which was made exactly for this purpose.

The small bulb is 20 watt. God only knows how this happened - the PO took the car in every 6 months to an indie garage for years. Maybe they put it in. Glad I finally figured out the weirdness. Why in the hell that sort of complexity would be introduced into the mix is beyond me.

At risk of beating a dead horse, here are some pics that make it clearer what I'm getting at. Is not important, but oddly curious. I'll take it to the dealer parts desk next time I need to go (once a year maybe) and ask if they've ever seen it.

The adaptor thing is not OEM. http://realoem.com/bmw/showparts.do?...93&hg=63&fg=20

Have you tried running a P21W bulb instead of it? I think that will solve your problems.

I agree with Simon. The adapters were sold as an "upgrade" to halogen bulbs. By using them you introduce another pair of potential poor connections. As problematic as the taillight connections are already, ditch the adapters and use regular Osram 21 watt bulbs with the plated bases.

Thanks for the info. I'm going to use the single bulb P21W from now on. I haven't swapped them all yet but I will. That's my thought as well - that an extra failure point is introduced into the mix with these things. I feel a tad foolish - I've had this first car for about 13 years. The first of these bulbs burned out about a month ago. Just a while before my reverse lights had gone on the fritz, I've been lazy about fixing them, so I took one of those bulbs to replace the turn signal bulb that had burned out. Then I got the rapid blink thing of one bulb only in the circuit a few days ago. In the past I'd jiggled the damned thing and it worked. No luck this time so I looked closer. Jeez, I should have noticed this sooner. Oh well.

Cool. I think that is what BMWFatherFigure was saying too (not trying to steal his thunder). Hope it works out.

While you've got it apart, give all the contacts in the assembly a clean, so you hopefully won't have to worry about it for another 13 years!

I have had real success with the Wurth Switch Cleaner. A little aggressive but removed oxide on contacts no problem.

I'll check out the Wurth. I wonder if it will renew window switches? I eat on the run a fair amount and bits of food likely find their way into the switches. I've got a few that I replaced - I mark them so I don't accidentally use them again but I've thought about cleaning them somehow.

Odd trivia, about 9 years ago, my after market keyless entry thing was still working but both of the clicker switches were getting intermittent (both switches eventually went belly up) - one day I was getting something from the fuel system of a boneyard Mercedes diesel, I forget what it was. I had my keys on the ground in front of me as I had a tiny flashlight on the key ring that was surprisingly bright - I had used it to see something. Long story short, some diesel spilled on the key ring. I'm thinking 'crap,' but funny thing is the remote clicker started working like new again. I had used electronic spray cleaner on them but diesel worked a lot better. Go figure. I should dip my old switches in diesel, see what happens.
