How do I change the Drivers side Head light? on 2008 GMC Sierra 2500 HD

I just can't get the Bumper from around the light I heard it had Black plugs I CAN'T FIND THEM

Are you trying to just change the bulb the bulb has to be removed from behind the light assy and you usually turn it counter clockwise 1/4 turn Or do you want to remove the complete light assembly
