Third brake light bulb change

Check in the vehicle where the light is located for round plastic plugs. I believe there are screws under them to access the light. Here are the instruction for changing the high mount brake light. Check out the diagrams (Below). Please let us know if you need anything else to get the problem fixed.

I am replacing the high mount light on the back of the car . The screws they sawy are stripped and they have to break the light on there to get it off and they may scratch or dent the car... then I will have to pay to have that fixed...
Any suggestions ?

I would replace the assembly with new bulbs already installed.
