2013 ssv holes from old lights

[newTahoeguy]

Just wondering if anyone has any ideas on fixing these holes on either side of the license plate, I'm assuming where the police had lights installed, currently they are filled with some type of clay or putty it seems like any input appreciated just looking for ideas until I can get to it

That looks like coax cable seal. It will keep the holes plugged until you decide how to permanently tackle them.

I’d probably clean it and put white 3m vinyl over the holes.

Or find some LED's and use them for additional backup lights. ?
(You'd have to run the backup wire to the liftgate, which is fairly easy.)

If you're @Doubeleive, you mount some radar jammers there!
