This is a how-to for installing an LED headlight conversion suggested by buzzvert and bought from Amazon. The scooter is my 2008 Buddy but should be the same for all Buddy's.

https://www.amazon.com/gp/product/B07KTXL7FW/ref=ppx_yo_dt_b_asin_title_o03_s00?ie=UTF8&psc=1

NOTE: Coming off the back of the LED itself is a set of braided leads and a black cable. In the pictures showing the LED installed, the black cable is shown on top but in reality the LED should be turned 180 degrees so that the cable is on the bottom. It has to be in that position so that the low beam LED element is facing up and reflecting off the upper portion of the reflector. I accidentally installed it backwards but have since corrected it but didn't retake the pictures.

Each photo will have an explanation but these are the basic steps:

1) Remove headlight surround by removing the single screw at the top.
2) Remove 4 screws located on the bottom instrument bezel securing the upper instrument bezel.
3) Unlock plastic clips securing upper instrument bezel with a flat blade screwdriver.
4) Lift instrument bezel high enough to get your hand or pliers (I used adjustable pliers also known as "Channel Locks") inside to unscrew the speedometer cable from the speedometer.
5) Lift off the upper instrument bezel and let it hang by the electrical cable
6) Unplug the 3-pin headlight cable from the headlight bulb.
7) Pull off the rubber weather guard.
8.) Release the wire clip that secures the headlight bulb to the reflector
9) Remove the one screw on the side of the LED that secures the metal collar as it comes from the box. There is a loose nut behind the collar so be sure to not let it fall to the ground and get lost. My kit had an extra nut and screw in the box but there's no guarantee that all kits have these. This collar will not be used so you can toss it. Save the screw and nut to attach the H4 adapter.
10) Install the 3-tab H4 adapter onto the LED housing making sure the black cable is on the opposite side from the wide tab on the adapter.
11) Install the LED housing into the reflector with the wide tab facing up and secure with the wire clip.
12) I re-installed the rubber weather guard but it can be difficult to get it around the black power module on the LED cable. I sprayed a little silicone lubricant in the hole to help get it over the power module. I wouldn't know but I can imagine this is kind of like a woman trying to past a baby except obviously one can't spray silicone to make it easier, Lol. I hope I don't get in trouble for saying that...
13) Connect the 3-pin LED connector to the 3-pin connector from the Buddy. I secured the connectors with a wire tie just in case.
14) At this point you can start the engine to make sure your new LED headlight is working and check to make sure you've got low beam and high beam and that they are correct (upper LED element lit and bottom one off for low beam, both lit for high beam).
15) Finish up by reinstalling the upper instrument bezel in the reverse order of removal. Don't forget to reconnect the speedometer cable. The threaded collar for the speedometer cable doesn't have to be super tight, just snug is good.

More installation steps.

There are two slots on the LED body, each 180 degrees from each other. These slots are there to retain the nut which helps secure the H4 adapter flange to the LED body.

The spring in the kit is not used.

Don't forget, when mounted, the wide tab and screw on the H4 adapter should be 180 degrees (opposite side) from the black cable coming out the back of the LED body.

Final thoughts.

I realized my mistake with the orientation of the LED body when it was first installed because I was seeing a high beam light pattern when the Hi/Lo beam switch was set to low beam. When I removed the LED body and looked closely at the H4 adapter flange I then realized there were two slots for retaining the mounting nut, each 180 degrees from each other. Dummy.

If I get the energy to take my headlight apart again I'll retake some pictures to update this how-to to make it less confusing. Sorry about that folks.

OK, my final thoughts on this conversion.

First, it's much brighter than the cheap, China bought halogen bulb that was in there.

There is a tiny bit of flickering that I can notice when the engine is at an idle but it isn't bad enough to bother me.

The light pattern isn't too bad, much better than the previous LED conversion I tried about a year ago plus the body of this conversion is small enough to not interfere with the speedometer. Compared to a standard incandescent bulb, there isn't as much spread in the light pattern, probably due to a narrower light source. Less of the reflector is being used thereby a more narrow beam is being thrown out. Still, it isn't bad. The brighter beam will be easier seen by cage drivers.

High beam to me is a little weak but that's OK since I don't use it much.

The H4 adapter can slide a little bit up and down the body of the LED which in turn changes what part of the reflector the light will hit. I may experiment with it to see how it changes the light pattern thrown out.

All in all I think this is a very worthwhile upgrade. The Buddy electrical system seems to be able to handle the load and the price is certainly right.

Thanks for the detailed photos and install steps. I was thinking about doing this to my Buddy 170i.
