I’m at my wit’s end! How do I wire this thing?
I’ve blown packs of [emoji[emoji6][emoji6]] amp fuses trying to wire this light!

Hi, @Travis_R

Perhaps it is me, but what I am seeing on my device is hard to understand;

Is there a way not to have special characters in your posts?

All the best,

With the 3 wires I'm thinking that it has a low beam and high beam. I'm wondering if they are switching the ground wire (brown) to turn it on and off. The green or white wire will be powered depending how much light you want. Powering both may draw too much amps. Any instructions with it?

Zero instructions with it.
With brown to ground and white or green to hot, the light is staying on, regardless if the switch on the light is on or off.

there is only one wire going to switch, how can it have a high/low switch.

as a basic tractor light, there should only be 2 wires going to it. this is weird. it has a white wire that is unswitched. almost like a remote switch controls light or its a lamp thats always on while running at a low level driving light, and the onboard switch controls high beam. you sure its a 12v light?

I thought Steve shared my link on how to wire this already?
The one wire is HOT and goes to a switch, then the fuse box to the + on the battery.
The ground just gets grounded to the fender or run it down to the chassis.

This is the schematic for your YM2500. The green marking is an on/off switch.

And the YM2610 basically has the same schematic. I had translated it into English.

Coming off the plow light, there’s a White wire, a Green wire, and a Brown wire.
The Brown wire is a ground.
The White wire is high beam.
The Green wire is low beam.

With the light mounted to the fender, the Brown wire grounded, and the White wire running to a 12v wire on the tractor (with the key on), the light is staying on, regardless if the switch on the light is on or off.
