Will this fit without removing my tailgate?

This mounts at the center rear — you won't need to remove the tailgate for installation. Exact mounting points and hardware requirements aren't specified, so verify fit before committing to fasteners or adhesive.

Do I need to prep or paint the black smoke finish before installing?

The black smoke lens comes ready to install as-is. No painting or prep work required on your end.

What if the LEDs burn out — can I replace just the bulb?

The assembly ships with LED bulbs installed, but bulb replacement specs and availability aren't confirmed in the product data. Contact support with your serial number if you need a replacement bulb down the road.
