Hello, I'm the original poster. For some reason, my guide was deleted. I will re-write it when I get the chance. For those interested in buying the headlight that I used, here is a link to where I bought mine: https://www.wish.com/search/45%206.5%20inch%20LED
They are going for $30 a piece. These headlights are basically drop-in replacements. You will remove your original headlight assembly from the plastic housing, and then take the reflector and glass out of the metal frame. Then, drop the new headlight into the metal frame, re-use the clips from the original assembly to secure the new headlight to the frame, and then re-insert it into the plastic housing.These lights come with an H4 type electrical plug. You can remove your original bulb holder, and wire the 3 wires going to it up to the 3 wires on the new light. This way, your high and low beams will work from the original headlight switch on your 3 wheeler.
The link I provided is to to the shopping site wish.com. Your headlight will most likely ship from China, and arrive in about 2 weeks.
Again, if my original post does not re-appear, I will write a new guide and post my pictures of the process.
