These are very self explanitory- they're just like the plates that came with your bumper, except they're pre- cutout for installation of lights. They are made of the same material and finished identically. My Nilights fit perfectly. They give the bumper more functionality and better looks. I only gave these 3 stars because I now have a pair of blank plates that came with my BR-20 rear bumper that I can't use, have already paid for, and likely can't sell. These should be an option when the BR-20 is purchased instead of an additional expense.
To the guy below who would rather not see the stamped part number: Just flip them around and swap sides L to R.
Everything lined up well, only discrepancy was the stamped number can be seen. Like they gave me two left pieces. I am working with the company to fix this. Not a huge problem really just being a picky whiny little brat 😁
