Hi unfortunately these are built in and may necessitate replacement of the light unit, alternatively if its the headlight bulb itself just drag the old bulb out and read its denomination off of the metal fitting, H7, H4 etc, I rather think if its the led bar it might be a retrofit from the previous owner as led bar displays became mandatory in 2009-2010 before that was just a single low output side light integral to the light unit.
