"00" 328i Headlights burning out

Greetings,
I have a 2000 328i. I have owned it for about a year and have
replaced the headlights three times.
Occasionally I get a warning light that states my headlights are out,
but the lamps are fine. I have also lost a couple tailights.
I'm suspecting a problem with the charging system.
Any thoughts?
thanks
Glen Ray

Measure the voltage at the battery with the engine running, all
accessories turned off. Different automakers have different voltage
specs, I have seen 13.5V +/- 0.5V, 14.0V +/- 0.5V and 14.5V +/- 0.5V.
Don't know what BMW specifies. Keep an eye on the voltmeter as you
gradually increase the engine RPM up to 4000. If the voltage ever goes
above 15.0V, there is a problem with the voltage regulator. Excess
voltage reduces lamp life dramatically.

Hed the same problem on 89 E30. After replacement of regulator on
alternator everything worked fine.

If it's any use, my E39 stays near solid at 13.8V.
