Ed,

The two lights are actually wired together.  It was done for "test"
purposes ... when you switch on the ignition.

An alternator problem will light both lights.

If you have any experience with these two lights coming on TOGETHER, please let me know. As I said, if one or the other were coming on, I'd look to see why that was, but I'm wondering if I have a different problem that makes the two lights do this at the same time.
