Have you cleaned the contacts on the plugs at the back? They are the weak link because they don't contact very well. You will probably need to bend them a bit to make a tighter contact. When you unplug them you will see what you need to do. They need to be very clean on both the plug and the pins on the lights. I had a lot of trouble with them on my 1988 1.5. If I had kept the car longer I would probably have soldered wires onto the pins. Our current 1.7 is working well with a clean up (touch wood). I was always worried about the visibility of the feeble single brake light on each side so, on this car I wired the two inside red lights, which are probably fog lights in Europe, as brake lights, giving me four brake lights, which is a big improvement. You also need to clean up the earths and give the lights a good clean out with soapy water to improve the brightness.

First, check that the circuit is working when you press the brake pedal. Attach a circuit tester or continuity light to the wires of the tail light and make sure you're getting current. If not, then check then bridge the contacts on the sender (pressure switch) on your master cylinder. If that doesn't light the brake lights then the problem is further forward in the circuit. If the fuses are OK then you've got your work cut out for you stepping through the wiring back to the power source.

thanks guys ive done all of that and it didnt work(it probly helped but didnt solve the problem), so i followed it and found out that it was the clips in the fuse box housing had come lose and didnt clip on to the relay tags properly.
