Ford Fiesta (95) Interior light Fuse??

Hi all, On wiring up a cigarette lighter to my Ford Fiesta (95) I wired the illumination bit to the interior heater back light, foolishly I accidently bridged the connection and blown a fuse? Now I have no interior lights (dash, elec. window switch lights, and heater back light) and have checked all the fuses in the box at the back of the pocket to the right hand side of the steering wheel and am now at a loss. Please help
