brake light help please!

[chamby]

well got in car last night and the light on the dash to tell me a bulb is out came on so i checked round the car and the entire rear right cluster has stoped working!
the indicator goes mental when i put it to go right but its only the front 1 working and the only light in the entire cluster that works is the fog light

ive checked the fuses and bulbs
all ok and now im stumped! never had this happen before

anyone got any ideas before it gets dark?
cheers

with them all not working , check the plug for the lights , incase water has got into it / bent corroded pins , it sounds like a problem with the earth wire maybe
