I have a 1993 300sd (w140)

In cold weather (32 degrees and below), the
idiot light on my dash comes on indicating
that I have a bulb failure somewhere. I look
at all the lights and they are fine.

10-15 minutes later the idiot light on the
dash goes out and everything is fine. I
figure that there is a marginal bulb some-
where.

Does anyone have any suggestions for testing
or is there something else wrong?

Check the third brake light and the tag bulbs.
