If your Landmark is like ours it most likely came with white obscure glass in the entry door. I didn't care for the look and it didn't match the rest of the smoked glass windows. The local glass shop was able to custom cut the exact dimensions with the same thickness in smoked glass to match the rest of the windows and had it tempered. Now when someone come to the door we can see who's there without peeking around the corner side window. Total cost was $20.00 and installation took less than 30 minutes. If you would like it darker just add limo tint for one way visibility.
