I can tell you that you haven't bought a shit headlight...or I can tell you the truth

:LolLolLolLol:
Your new light most likely uses the bulb that is found in kitchen downlights. Nothing wrong with that in itself, they are commonly used as auxillary lights.... but you are going from 110w stock to 40w with your new mask.... I would not ride with that at night bud...
Now as for your wiring, I'm going to get straight to the point here. Those red/yellow & red/black wires ARE your hot wires. I don't know what that brown wire is from but DO NOT use it. It is NOT part of your headlight circuit.
Now your new headlight poses an additional dilemma...
Your stock headlight setup uses 2 dual filament bulbs. This means that each bulb had both a High & Low inside it.
Your new headlight uses 2 single filament bulbs. This means that each bulb has only one function, ie there is no High & Low, it can only be used as one or the other.....
Here lies the problem. Your stock Low wire has no power when you flick your switch to High, and vice versa... You can't just wire one of the new bulbs to the Low wire & one to the High because you will still only have one bulb on at either switch setting.
To have the functionality of a Low/High, you need to use a relay. Now you can use 2 relays, one for each of the bulbs on your new light...or you can use 1 relay to power the bulb you want to use for Low, and use your stock High wiring to power the other bulb.
I'll only outline using one relay for you here. There is a thread on this here:

This is for if you want to use one relay:
So for the above setup, terminal 87 goes to the +ve wire of the bottom light on your new mask (assuming you wish to use the bottom for Low).
Terminal 85 goes to the blue/yellow wire heading into your switch.
Terminal 30 goes to the +ve side of the battery and terminal 86 goes to the -ve side of the battery or an existing -ve wire.
The red/yellow wire goes unused and the red/black wire goes to the +ve wire of the top light on your new mask (assuming you wish to use the top light for High).
The -ve wires from both new lights in your mask go to the stock -ve headlight wire or -ve battery terminal.
Of course you could get away without using a relay. Your new mask uses well under what your old setup used so you will be perfectly safe to not use a relay. I do reccomend using a relay though as you can go on to upgrade to a better headlight at some stage without having to rewire....
To wire your headlight without a relay simply choose a light on your new mask that you want to use for Low, take the +ve wire from it and wire that into the blue/yellow wire that goes into your switch block.
Now take the +ve wire from the other light and wire that to the red/black wire coming from your switch.
The -ve wires from both lights go to the existing -ve headlight wire or to the battery terminal....
I hope this has helped.
