Front and side views of the batwings

Front shot showing the cutouts where the lights will be installed

Here is a shot that shows the distinctive batwing flared design of the wingtips. This is pretty much a Van's trademark, and is one of the easiest ways to identify if the airplane is a Van's RV or something else. I'm not sure if there was some aerodynamic consideration for this design, but knowing a little about the designer of the airplane and his background, I would imagine that there is.
