Hi. Newbie here. I installed the high/low beam LEDs. Pretty straightforward plug and play, other than trimming a little rubber from the boot. Awesome amount of light.

Once the old bulbs are removed, you slip a ring into place where the old bulbs were and hold that in place with the stock spring. Then the bulb fits through the ring and twists into place.

DO NOT drop the ring or you will be fishing for it or disassembling your fairing. (Personal experience.) To prevent this, use a bamboo barbecue skewer to guide it in...push one end through the hole in the headlight reflector where the bulb protrudes through, slide the ring down it, push it into place, and then close the spring. the rest is plug and play.
