Tom: Just get two sets (for the left and right side) that fits between the louver's opening. You can flip and mount them up side down with double stick tape (that come with it) underneath the louvers. You can also add a very thin bead of silicone glue around the perimeter before you press them into place. This will help to seal up the edges from allowing water to capillary between the units and the louvers while adding extra strength to secure the unit to the louvers. And do clean/scrap off the excess oozed silicone glue. I have two sets of LED units that are about 16" long which were mount about five years ago and they are BRIGHT and they do not interfere with my back view at all. They do look "right" and are not obtrusive or gaudy. I can send you pics just, forward me your email address.
