    Plugged in the lights this year and half of them aren't working - they're icicle, LED bulbs like these

    http://www.homebase.co.uk/en/homebaseuk/300-multi-function-bright-warm-white-led-icicle-lights-371120

    The LED bulbs are the same thickness as the wire and can't be removed.
    A couple of "icicles" will be working, next 3 won't work, next 2 work etc.

    Should I just start at the plug end, cut out the non-working icicles and join the wires ?

    No don't do that please I doubt it's the individual LEDs that are finished, most likely a circuit issue.

    I'd either leave them in to be fixed or just replace them, LEDs like that are not designed to be replaced individually

    Not trying to be a smart arse here but would you not be better off binning them and buying a new set rather than getting them repaired? They're so cheap these days

    They're wired with a handful of LEDs in series on each leg and use the voltage drop across each led to limit the current. If one fails the whole leg goes out. Bypassing one will increase the load on the others on that leg. Bypassing the entire leg should be ok in theory as they're paralleled.

    That said, just bin them.
