Last year a friend of mine did this on his Kymco S125 and explained to me how he did it.
After you remove the nose plastic, it is pretty simple to splice into the wires for power. You always want to make sure that your leads on the LEDs never touch and short out your system. I used really bright yellow LED bulbs that I got from a guy in
Since there isn’t really a bulb housing, I used a round file to make the hole big enough to push the bulb in and used silicon to hold it in place. Also think about using using rubber as well as a possible mount along with the silicone.
Remember you also have to include enough extra wire so when someone has to take off the nose to do something, there is no strain on the wiring.
