No tail lights

2009 subaru legacy has no tail lights when headlights are on. It has turn and brake lights but for some reason no running lights. I've replaced the bulbs and checked the fuses, also replaced the relay. Not sure where to start looking.

I'd back way up and diagnose it instead of throwing parts at it. Where does power end in the circuit?

Agreed. Get a wiring diagram and start chasing volts starting from switch all the way forward.
