I am attempting to install trailer lights to my 2013 XTS. Cannot determine how to remove rear lens. No videos available . Searched google, You tube etc..

You REALLY don't want to do this !!!!
Replacing the taillight lens:

Jack up the car
Remove the tire and wheel assembly.
Remove Rear Wheelhouse Liner: (See instructions)
Release the Rear Bumper Fascia (See instructions)
Remove Rear Compartment Floor Panel Carpet (See instructions)
Remove Rear Compartment Side trim panel (See instructions)
Remove the Rear End Trim Finish Panel (See Instructions)
Unplug & remove the taillight assembly

Yikes! Sounds like you'd need a union card to change the lens.

Yea, the dealer wants $600 labor & $350 for the tail light assembly ! Ask me how I know.
I did this, but it's a PITA. !
