    Default Reversing lights/switches

    It's now necessary to have working reversing lights on our horse lorry for the test - this has never been the case and they have never worked.
    The switch seems to be running (or not) from the driveshaft, but I can't find a replacement.
    Would it be acceptable to wire in a manual switch on the dash or does it need to be automatic?

    iirc it can be manually operated but in that case there must be a warning light visible to the driver

    Could you fit a switch on the gear linkage? Maybe a proximity switch.

    That's the other option, i could put one operated from contact with the gear lever, just its easier to put one on the dash.

    Thanks for finding that - I'm not good at finding things.
    Seems I am ok as vehicle is pre 1st September 2009 - if I'm reading it correctly that is.
    I think I'd best ring the testing centre tomorrow, I'd hate a failure and six week wait for another test slot just for reversing lights.

    The important word is "may".
    I would translate that as must work IF fitted. Otherwise, illuminated switch on dash. But do check with the tester....not the test centre.

    Age as well as if in some cases. I have ABS so that must work for MOT or at least the light should. As my motor was built before ABS was compulsory i can legally take out the ABS system. If my temperamental sensor does not stop pissing me off every two or three days that may well happen soon

    But you have to remove ALL of the ABS...is that practical?

    Its quite easy. I only have two lined from the brake master cylinder going into ABS pump. Four lines coming out so just make up two new lined with splitters on then bin the Pump. ABS ECU is under the dash what is easy to get out (13 screws) then take the sensors out. You are allowed to leave the rings if they are part of another item like hub ir drive shaft. See 2nd last paragraph on the left here https://www.mot-testing.service.gov....4s03000401.htm

    And then fit a braking compensator as fitted to cars pre ABS?

    Transit ones up the rear are identical to the ones what are on the non ABS versions. Not that hard an obvious job to do.
