I struggled for half an hour trying to get the drivers side led in . I have pretty big hands and it was impossible to hold the bulb holder with one hand and push the led in with the other .
Got it sussed now though . Get a piece of 10mm plastic tubing , put the led in the end of the tube , hold the bulb holder with one hand and push the led into to holder with the tube . Only takes a couple of seconds now
If your wondering what the black tapes for . I could only find some 12mm tubing so i cut some slots in to make it a tight fit on the led .
