Brake light bulb replacement

The information you responded with is for the brake light on the corner of the car. I am referring to the strip of lights that is along the trunk lid where it meets the bumper next to the license plate. I removed the carpet lining from under the trunk lid and removed the nuts from the bolts that hold the light strip in place but cannot remove the light strip to access where the bulb is. These are not back up lights. The trunk lid has a red strip for brakes, then a white strip for back up and 2 red blocks on either side of the license plate that come on when you apply brakes. I am not referring to the additional lights that are on the corner of each side of the car which come on when the car lights are on and brighten with braking.

Thank you for your reply but yes these are brake lights. They are red and they only go on when you put your foot on the brake. I would consider that a brake light. There are about 12 bolts that hold the panel that goes across the back of the car on the truck lid. The panel is loosened from the car but I can not pull it away far enough to access where the bulb is. It seems that there is something else holding it in place. Any idea what??

See pic attached - The car was purchased used and apparently there had been a slight fender bender which resulted in cracking one of the red lenses.

Thanks again, but these pictures do not reflect what I see when I open the trunk. There is no strip on the outside to remove. The lights go downto the bottom of the trunk lid - where the lid touches the car when the lid is closed. There is nothing removable on the exterior of the car. You have to remove the carpet padding from the trunk lid and then remove the bolts visible under that. This is a Seville if that matters. I have not been able to find a picture that correlates to what I see when I look at the car or take it apart. Unfortunately, I did not take a pic of when I had the car apart last night. It does not look anything like the diagram you submitted. The lights are in one piece - on either side and on top of the license plate.

Ok, I can see that this is how you remove the top red strip light. I am not trying to remove that light/lense. I am trying to remove the lower strip that includes the white back up light strip. The bulb that I want to replace should be in the 2 square red lenses to the side of the license plate. The one on the driver's side - the red lense is also broken - therefore it looks clear in the pic I attached before.
Are you telling me I have to remove the top part first to remove the bottom? If so, I still don't see any way to remove the top part from the outside. Is it possible to replace a bulb in the bottom strip as I described? I have not been able to locate that whole piece from a junk yard yet.

I have highlited in red how the trunk closes - it meets the bumper under the license plate. I have highlited, in yellow, the set of ligts/lenses that are connected to where I am trying to replace the bulb and have pointed to the specific area where the light is out with a yellow arrow. The area that houses the license plate also seems to be part of this set of lights/lenses.

ANSWER IS ON THE NEXT PAGE

How do I get access to my brake light in the trunk lid so that I may replace the bulb? This is like trying to break into Fort Knox! I have given it one attempt but it seems that I may need a special tool to continue past my recent progress. This is the latest model auto I have owned so I have never encountered such nonsense to replace a bulb. I typically own '70 or '80 vehicles so this is new to me.
