The Lights do not come with the bumper. We recommend any light up to 3.5-4" round. Diode Dynamics SS3 Lights will work great in the light port and can be found in the Lighting section on our site.
The lights can turn on when backing up if they are wired that way. (You will need to tap into the existing reverse light wire to trigger these lights)
The plate you are referring to is the Aluminum tread plate that is on top of the bumper and does come with the bumper. It is on the bumper in the product shots, but there is not a top view to show the logo etc. but it is there.
