Ocean Cycle Challanger
Here is a nice design made to fit on the popular ICE trikes. It can be bought assembled or as a kit. The website currently says it is in prototype stages, but says the production model will have wing mirrors, signals and lights using LEDs. They appear to be looking at a blower for the front windscreen also. The fully enclosed design also features a manual wiper for the front screen. The windows are said to be made replaceable and are not difficult to replace. This one should be an interesting one to follow.
