Replacing headlights?
 

I just bought a nice slightly used 2016 Yamaha gas cart. Driving it home in the dark for the first time last week I thought that the headlights were not very powerful. When I got home I noticed that the lights were not LED but incandescent. So my question is how do I replace the "old fashioned" headlights with LEDs? I know I could let the shop do it, but is it that hard to do at home? Looking on Amazon I see many replacement kits, but key factor seems to be what "G" model my 2016 cart is? How do I find that out, and if I buy the kits is it a fairly simple pull and replace fix?
Thanks!
