This will allow enough room to remove the (4) T20 screws to remove the cover to access the igniter and bulb. There is one T20 that needs to be accessed from the gap where the turn signal was. It is a little difficult to get back in but with a magnet you can get it into place and then tighten it. Total time from start to finish is about 10 minutes.
