Which fuse for...?

Noticed the other dark morning that my o/s rear light, sidelight and dial dash lights were not working. The dash light showing that the lights were on was not working either. The blue light indicating main beam on was fine as were indicator/hazard.. Headlights/main working ok. I'm thinking fuses at the mo but not sure which fuses are for what?
