Hi there,
I have a 2000 E39
Yesterday my dashboard indicator came on and said a right rear tailight is
out.
I changed what I thought was a burn out bulb seeing it was all black. The
indicator still says there is a light out.
I tested them all and none of them are out! I reseated them and still no
luck.
What could be causing this?
Thanks,
Jeff

Replace all of your tail light bulbs with NEW bulbs.
Solved the problem for me last spring.
It only takes a tiny bit of corrosion to fool the computer into indicating a bulb is out.
PS - Don't forget the 3rd brake light in the rear window.

Replacing brake lights is a rite of passage for new BMW owners. I bought a
used three year old 528i and have replaced the brake lights at least five
times. I also got fooled by the third brake light once before. My
suggestion: buy a pack of 3-4 bulbs and keep them in your glove box or
trunk. You will need them!

I've had a lot of problems with corrosion on the bulbholders on this
model which will give the symptoms you describe, remove the holder unit
and clean all the connections especially the contacts to the bottom of
the bulbs. Hope this does the trick. Cheers Clive

There are two tail lights on each side. You fixed one.

The light sensing circuit is know to be very finicky. Sometimes a worn bulb
will be enough to cause the indicator to go on. The standard fix for this is
to replace all the bulbs when one burns out. Doing this has stopped the
problem you describe for me.
Good luck.
