My coupe light configuration dont make sense

I can get the head lights on by them selve,
Or the tail lights and corner lights on at the same time,
But Not the tail light on with the head lights.

I changed all my tail light bulbs and head lights blinker bulbs all new..
Changed most the fuses ...

Maybe it's not a problem just how they are made if you know anything about this
Let me know
Thanks !!!!
