    All the brake lights on my swift sundance have suddenly all gone out, the bulbs are fine, the fuse is fine. Anyone any ideas as to what my problem is please?

    Check the switch on the brake pedal!

    I guess the next place to look is the actual brake light switch at the pedal make sure that the pedal is making contact

    Sounds like you have a short in the circuit!
    If your not familiar with a multitester it might be worth the £50 to get an auto electrician to look at it!

    Check the circuit anywhere the wires move / chafe.

    The switch area, as previously suggested, sounds a good area to start.

    I'd remove both the bulbs and check the holders after that.

    You really need a multimeter on the Bulb/switch side of the fuse mounting (with the fuse removed) + lead on fuse terminal and -ve on chassis using resistance reading.

    With bulbs in , Get someone to operate the Brake switch/press the lever down.

    You should see some resistance and not a full short circuit/zero ohms reading.

    Try it with bulbs out.

    With lever pressed you should see open circuit/infinity ohms reading.

    If there's a reading check / move the wiring with the meter still on. If the reading fluctuates, you are in the area of the fault.Then a full visual should , hopefully find the problem.

    This saves blowing loads of fuses and possibly causing damage to the wiring.

    or if you wanted to become familiar with a multitester look at these:

    Analogue Multi Tester
    Standard Digital Multimeter

    It's a shameless plug I know ! :Wink:
