Question Headlights on E34 go out for no reason

Hey all, I have a 1990 535i. When I am driving at night sometimes the headlights go off for no seemingly no reason. It does not coincide with me hitting a bump or anything like that. They will stay off from 10 seconds to 2 minutes and then come back on again. Has anyone ever experienced this? Does anyone have an iodea of what this is/could be? Any help is appreciated.

Dear Tim,

This link should help you. Likely LKM going bad, but new LKM unit is very expensive.
With basic soldering skill, you can tackle this project by fixing your LKM:

Soldering is much easier than you think

A soldering kit costs about $15 or so.
Get a throw-out radio or some old circuit for practising soldering skills.
It is basically meting solder to join circuit.

Not rocket science.
Also look online video like Yahoo video search, some websites will show you how to solder. Example:

Good Luck.

I'm looking at a couple of LKMs on ebay. If I can get one for under $20 I figure that would be worth saving me the trouble of having to repair my current messed up one. Thanks for the advice guys.

OK I just went out to my car to pull the LKM out and it won't come out. It seems like it is more to it than just pulling it. Can someone tell me what in the world I need to do to get this thing out? I pulled with all my might and the sucker ain't comin' out.
