Default Tail lights not working but break lights are help

Hi guys - I have a CBR600f (2003 eu/uk model) and cant work out why my tail lights aren't working. I have bought new bulbs and tested the circuit on them so I know both filaments in the bulbs are OK. The break lights come on both bulbs when pressing the rear brake but there is no tail light at all. Not sure on the different variations in the bike but there is no light switch (except for the main beam) so assume they should come on with the ignition.

Everything else is working including front light, indicators, neutral light on dash so don't think its the fuse as from what i can gather they are all on the same one

Anyone any ideas on things I could try?

Hmm... I've got an '06 model and the only lights that run constantly in the rear are my main brake and license lights. The rear indicators only come on when I hit the switch to turn. I, too, find it odd that the rear indicator lights remain off while the front ones stay on. Hopefully, someone will drop a knowledge bomb on us!
