Brake Lamp Replacement

[KidGalahad]

Hi:

I have a 2007 Buick Lucerne CX. I need to replace both brake lamp bulbs and I have purchased the bulbs, watched the online video, etc.

I have removed the panel but don't have the right socket to remove the bolts to that secure the housing.

What do I need to buy?

Thanks in advance.

It's a 10 mm wrench. Mission completed.
