if fuse ok, and bulbs ok check for shorts or it could be the tail light sensor.
i was about to replace my sensor as i was having intermittent proublems. i would have to turn key on and off a few times to get it to go off. when "on" the tail lights where not lit up. it was happening often thus the research, but then it stopped only happened once in the last 4-5 months.
