No Running Taillights

[Atmosphere]

A friend of mine currently does not have any running taillights, though his brake lights still work as they should. The car also fails to chime when the headlights are manually turned on without the key in the ignition. We believe it has something to do with the license plate light as immediately after it was tapped for power (another story) the running lights stopped coming on.

All fuses on the driver side seem to be intact. Any ideas on how to remedy this?

Thanks.
