The amber corner is held by a screw and clipped into place. No need to break anything while removing it =)
Mind you, once you remove it, you'll have a square hole underneath it..
After thats done, get yourself some chrome turning signal bulbs to replace those fugly orange ones =)
Just be careful putting those headlights in your oven! Keep the temp low, and even turn it off while you put your headlights in.. I know from a bad experience! LOL
