I have a buddy that went with the ebay version on his Electra-Glide from Halogen and the difference in seeing at night was huge, but I don't see much the point on a 2016 Road Glide as we already have LED and the spectrum of view is great. I already have on-coming cars flashing me their brights thinking I have mine on.
I think there is going to be a point where bikes and cars are going to have lights too bright and start causing accidents because you can't see. Emergency vehicles are already getting to that point where people are drawn to the lights when blinded and running into police cars.
That being said, I love the LED headlights, they just need to be within reason. Unlike the idiots that have the off road 4x4 LED bars on driving on highways!
