Tail lights quit working...bulbs are ok

tail lights inop..brake lights turn signals fuses ( in fuse block under hood ) ok...parking lights all around went out same time

TAIL LIGHTS STILL OUT...LOOK OUT FOR ME AT NIGHT!!!!..SAMBO

Since all the fuses are ok and all the lights went out at the same time, I would lean toward the light switch having gone out. I can't say for sure, as I don't know how these G8s are wired, but thats where I'd start checking.
