e53 center headlights dead - ground? LCM?

My 04 e53 center running lights recently went out, together, same time. I replaced the bulbs, headlight switch, high beam/directional stalk switch, checked the fuses. I'm thinking it's a ground somewhere. I have the Bentley Manual, but can't make any sense out of those diagrams.
I had them coded to stay on all the time.
I'm pretty sure I checked about the relay, and the LCM was replaced a few years ago, although I wouldn't dismiss that part.

Nothing shows up on diagnostics at the auto parts store...

Anyone have this problem? I'm thinking its a ground somewhere. How to test the LCM?
