You should be able to squeeze the clips together and the light will simply pull out. The clips are around some hooks, so they may need to be squeezed and maneuvered around the hooks that hold the light bulb assembly in place.
Just be careful with the rubber boot, sliding it down the wires, as I pulled one of the wires loose from the fixture, and had the remove the whole vertical light assembly to fix it. All the high beam, low beam, and running lights are replaced that way on my 2013 that has the vertical light (Anthem and Aspire in those model years, Cornerstone lights were horizontal)
