    Fitted 2 rear led indicator to my 2014 sport. They were flashing fast so I fitted resistor. Worked perfectly with ignition on but when start the engine they won't work . Any ideas ??

    Are they wired correct way around?
    LEDs are polarity sensitive and if reverse wired the charging circuit may give them wrong current flow.

    They work flash fast without resistor perfectly with resistor and ignition on. When I start up they won't work I must be doing something

    Do you have a multimeter?
    If so disconnect one indicator and measure voltage both ignition on and engine running but also note current flow direction in both states.

    Does the 2014 model use CAN bus? this will cause all sorts of problem when using different bulb loadings.

    I only had success fitting led winkers when I used a genuine triumph replacement relay on a couple of bikes.

    Downside is they're expensive for what they are and they need to be earthed somewhere.

    Generally any flasher relay intended for LED bulbs should do the job some are rejected if the system uses CANbus...its a very sneaky move as the system can be tailored by the makes to be very picky with component specs, had no end of trouble with some Japanese car systems especially audio when they are integrated.

    Haven't a clue all I know there is no relay for indicator it's built in to the Ecu I'm told . Funny enough it works fine when ignition is on only when engine runs ice nothing . think it's time to go back to bulbs
