Concur about checking the easy stuff first!

I was able to sneak some time today to look at this.

Visually the wires, connector and ground behind the lamps in the engine compartment looked good.

I removed the lamp, pulled the connector and while it was a bit difficult to remove everything looked pretty good when I got it off. Cleaned both sides with some contact cleaner, put a small dab of dielectric grease on the lamp tabs and put it back together.

No apparent change though; the right low-beam was dark. I did not drive around to see if it would come on after a few minutes like it usually does; will find out tomorrow on the way to the train.

One thing I did notice though... which I should have checked initially is that when the high-beams are on, all four lamps are lit. Back to low-beams and the right lamp is dark.

So this weekend I hope to find time to pull the lamp again and check the voltage at the connector, and perhaps swap with the left side to help isolate the issue.

Thanks to all for your help.
