My '91 525i headlights only go out periodically as I am driving down the road. Seems to be no consistentcy to it. They will either come back on themselves within 5 to 20 seconds or I can flick the highbeams several times and make them come back on. Anyone had this problem?

Mine had a shortcircuited battery and I never even noticed it except for those flickering lights... (battery even had some cracks so it didn't explode but after 7 years, what the heck, the car now starts a lot quicker)And last week I changed the battery for a new one, and no more problems, weird but it's a fact.<p>Hope this helps, anyway it's not an expensive solution.<p>Hans.<p>'91 520iA 183.000km<br>'93 316i

Check/resolder or replace the lamp control unit. It's under the hood, drivers e box side. Big black module on the outside side of the box.<br>

I would agree to the other response that the Lamp Control Module is suspect.<p>Occasionally, my car's right light would go out and I wouldn't notice until it came back on. The answer I got from the Brett Anderson was the lamp control module.<p>One day while the hood was up, I tried to remove the LKM to see what it would take to open it up and look for any obvious problems. It wouldn't come out easily, so I just made sure it was pressed down correctly.<p>That was about 4 months ago. The lights have worked consistently since then.<p>Andy Peavy<br>91 535i<br>email: apeavy@yahoo.com<p><i>: My '91 525i headlights only go out periodically as I am driving down the road.

Roger:<p>I had exactly the same problem with my 89 525iA. It turned out that the soldering had cracked at the control unit and it was a minor job for my shop to re-solder the connections. That was about two years ago with no problems since.<p>Fred Meloan

Take out the LKM and remove the board inside. look VERY closely at the back fo the 4 relays on the board and resolder. Should solve your problem.<p>Fixed my problem

BTW, all your lights are controlled by this little Hella circuit card. I had the car going in for an inspection anyway, so i asked them to look at the lo beam problem too. They resoldered the legs of all the relays (charged me $50 labor) and it worked great for about 2 weeks, then same thing again. This time i checked it out myself...it looked like Ray Charles did the soldering. I removed the globs and re-soldered it. I also put a small wedge of foam rubber on the edge of the circuit card since i believe it's the constant vibration of this card in its little plastic box that causes the solder to crack. Anyway, it's been almost 2 years without an LCM problem. And no, i didn't get my $50 back....yet.

Thanks you guys I had the same damn problem, light flicking on and off, so anoying. Did as you said with the soldering of the circuit board and hey presto the problem has gone!!<p>Paul 535i SE `90
