Turn signal lens question

Hello, I was wondering if any one knows of a turn signal lens that is clear and does not have the fluting/ribs built into the lens itself. Reason is I was thinking about cutting away the housing and mounting a fog light behind it such as a Hella FF75.While keeping the lines of the bumper clean and protecting the light at the same time.

The only other way of doing this is to take the lens off and grind /sand the flutes out. Can anyone recommend a good method of separating the 2 pieces.

Thanks for any help or opinions you can provide . Ray M
