Good. So this is on my 2019 RGS. I bought this because I don't want to pay ridiculous prices for Kuryakyn, Ciro3d, custom dynamics or XKglow packs. Although everything I mentioned is above. I don't scold them at all. You just don't pay for it. These LEDs I bought here are just as good and a lot cheaper. If you're not mechanically inclined, ask someone to do it. If you want to learn how to connect the cables to the battery, watch the video of a law-abiding motorcyclist. They have one that shows how it's done. I have no idea about the blue wire although it is connected to the brake line so the LED turns red when the brake is applied. Speak to a Harley technician or someone who is knowledgeable and they can help you. I wanted to do it, but I don't care. All functions work as they should and the music in the uploaded video is better than xkglow. The Xkglow product requires something weird to buy music and somehow connect it to your phone, which I don't understand. This one just listens to the music coming from your bike and flashes the LEDs accordingly. You can buy any item you want, but this one is just as good as the 3 and 4 hundred.
