How can I replace the license plate bulb

I have an Accent 95 hatchback base version, and I need to replace the bulbs above license plate.

I know that I need to remove the black plastic cover first.
But this is the problem. How can I remove this plastic cover without break it?

I finaly found out how to replace these license plate lamps.

I open the trunck, removed all the 15 screw that retain the big brown plastic panel.

Then remove the panel and remove the center stop light (3 mores screw).

Finaly, remove directly the bulb housing by the rear by unscrewing them with the hand.

And remove the bulb from the housing.
