I get confused with the various model Harleys.......Not sure if your FLTR has a normal (large) 7" headlite or maybe smaller?
If it's the 7" like on my SE Ultra, then you can buy it straight from Harley. Go to your favorite HD store and they'll fix you up. I think they make the smaller one too. Plus they also have the 4 1/2" size in LED for the passing/aux. lamps too.
They are $$$$$ pricey, but (hard to believe), but buying them from Harley might get ya the best (still expensive) price. Those units are made by JW Speaker Co.

There is also another LED lite called (Trucklite), that some have installed. It has a totally different look about that I don't care for, but it still is LED and performs well too.

Here is a good write-up on the two of them with pictures...............check it out.
