why does my fuses keep blowing 4 my brake lights n reverse 4 saxo t reg ?

you have a short circuit in either your stop/rev.lights,does the fuse blow when you apply brake or go into reverse?check for wiring on each circuit rubbing through/chaffing on body or other obstructions,had faulty bulbs/switches also causing problems,have a quick look at reverse light switch,had problems if they are near the selector mechanism where wiring can be rubbing on moving g/box parts
