Fuse for Taillights on 550?

Is there a fuse for the taillights on the 550? I'm having intermittent issues with park lights, fog lights, instrumentation lights, and license plate lights not working though the fuse for this circuit is good. But now I have no taillights which has nothing to do with this circuit, or at least the manual doesn't say so.

Looking in the manual, I don't see anything clearly listed as taillights. I do see a relay called "External lights", however. Are the taillights on this circuit?

Headlights work, signals work, hazards work, dome lamps work. That's it.

Thanks.

 

If anyone else ever has this same issue, the relay labeled "external lights" controls this circuit.
