How can I replace tail light?

I am trying to find out how to replace light bulb on my 98 LaSabre trunk door (red parking light)
Any help?

You can register with Buick and view the owner's manual, which should help.

You need to take off the lens assembly.
There are 6 wing nets holding it on under the inside trunk liner.

Thanks!!

Hold it carefully as you take out the last of the taps under the fibre sound cover on the trunk lid. The whole unit is hard to keep in place and wants to fall.

You are right!!! Who design this?
