I have attached the wiring diagrams for the 2012 onwards fender, for the headlamp levelling and indicator lamps. 2010 is similar but the connection references will be different. Pure guesswork; if the levelling motors are running the fault is not with the motor (are they both running?) but might be with the internal switch or diode. Another speculation is that the levelling motors share a common header earth with the indicators. As you have fitted new LED indicators, are they back-feeding the levelling motors through the earth? And are the earths in good order?
Click on them & it downloads, thats cool
