New un-used Black Rhino License plate kit
Can't post a link to their site but if you search it you'll see the license plate installed.
From their site:
Here's a great way to mount your license plate to your Rhino.
The mounting bracket uses the existing tailgate hinge bracket for the bottom of the mounting plate, and is designed to fold down along with your tailgate. The license plate frame includes a light to illuminate your plate, along with a 3rd brake light. The mounting plate is large enough to include an off-road sticker also, in case you find the need to run both a license and an off-road sticker.
Includes all mounting hardware, along with a harness that simply pigtails into the existing wiring for simple installation.
$80 new, asking $50
