Google doesen't say a lot about that particular device. And of course we're not talking here about winglets or proper wing tip fence (like Airbus or PZL-101A).
Google so far gives me a tip that it can be connected with shielding pilot from the lights (landing or strobe). So as you can see it differs a bit from your theory and thats why I'm asking about some evidence of your statement.
