Press down on the tab and you'll hear a small click, while maintaining that pressure pull it apart. Dont be gentle with it or itll never work. ALSO remember to cut the zip ties that holds the plastic wrapped bundle of wires the metal harness attached to your light. I uninstalled the metal bracket since it no longer served a purpose.

 

Use a small screwdriver to push the tiny tab down and pull.

 

Been tryin for the past 3 hours the tab is all deformed and knicked now. FML

 

Are you pulling on the harness as the tab is pushed in? That's all I had to do for mine. Also if this is your first time ever taking the lights off the car, there is a white zip tie holding them down you'll have to cut.

 

Got it! Thanks. I was being too gentle with the thing and not applying enough constant pressure on the tab and the zipties were a b***h to get a hold of.
