I bought the complete LED turn signal conversion kit for my 2014 SGS Item: GEN200-KIT-BCM. I have H-D passing lamps so I selected the red rear and amber front kit without the white Dynamic Ringz.
Wow, they are like burn your eyes out bright in a straight-on narrow beam and not so good off axis out of the main beam. A diffuser is needed to spread the beam pattern.
I found some diffuser sheet made for LED signs here: Acrylite LED
It is a colorless diffused sign grade acrylic .118" thick plastic sheet with a matt finish on both sides. I ordered a square foot of it and cut out some disks using an adjustable hole saw in my drill press. The disks drop into the bullet turn signal lenses like this:

Here's some pictures of them off, and on at running light power. They look pretty much the same at most angles of view now and are still more than bright enough. I really like the way they light up now. The amber individual LED's show up bit more than the red ones.



Here's a video (diffusers installed) way off to the side with the turn signal on. It's still so bright that my iPhone can't capture it with correct color:
