First you need a 12v circuit. So you need to buy a DD-DC converter, a fuse holder, and switch(es).

The red and black are for the normal mode. You power with the red+, and switch modes with the 3 other wires-, work light mode is black, DHO is yellow and strobe is white. DHO needs a solder and a gasket is missing.

In the rating/comments section of the product page, you will find instructions and pictures. 2nd comment in Russian.
 
It has 4 wires , black , red , yellow , white. I took it 12v because i have kt controller and seller told me it has light 12v https://nexun.pl/czesci-do-e-bike/kt36-48svprc-36-48v-30a-sinus

The light output on KT controllers is good for 100mA, so if the output is 12V, then that's 1.2 watts. The light you posted a link to is 30 watts. I'm pretty sure you didn't ask the seller about the light you intend to use, unless you did and he lied to you.

Yeah about that before 40 hours i have sent the question, zero answer, im going to resell it . If kt is not able to give so much power. Gona wait 5 more month for nuculus, i think he can give power that i need
 
You don't have to run the light from the controller. Run it from the battery.

There is a gasket between the lens and the DHO plastic sheet, but there must be one also between the DHO and the casing. Maybe they solved the problem and now include this 2nd gasket, I don’t know. The info is from the russian guy who had bought two and explained in his comment how to plug and fix them properly. DHO is fog light mode, that is achieved by passing the current through the plastic sheet that is behind the lens. I don’t believe that you need the strobe mode, that is very irritant to upcoming vehicles.

But i use triangle box battery from upp, im using 3 batteries a day 48v 20ah for deliveries, so its needs to be swapped fast . Thanks for all advices, kind od lame for 12v but what can ya do :)) thanks guys for all.
 
False problem. A DC-DC converter does install on the bike, not the battery. When you swap and plug a new battery, it doesn’t change a thing that the bike has a 12v circuit. When we say take the current from the battery, it does mean on the red and black controller wires, not the battery wires. A 12v accessory circuit is the most universal automotive standard on all sort of vehicles.

I use a power meter (with Anderson plugs) that has a tap (JST 2-pin plug) for 10-80V lights and 48V horn. If you don't want the power meter, you can just have an Anderson (or whatever power plug you use) on each end, with a tap for the lights (JST, 5.5mm DC plug, or whatever).

You can also add the power tap directly to your bike's battery plug.

I find a 12V system to be an unnecessary and unreliable complication.

The complication comes when you want to add a tail light. I have two of the high voltage headlights, which is great for offroad night riding, but high voltage tail light choices are pretty slim pickins, yet a lot of people that ride on the street want them.

I’ve never had trouble finding one. Last time I got one of these, though I got it from eBay: https://www.amazon.com/Adealink-Taillight-Indicator-36V-48V-Electric/dp/B07Q9JBS91
The turn signals are so dim as to be useless, but it’s otherwise good. I wired stop and tail together for more brightness.

There are others on Aliexpress:

https://www.aliexpress.com/item/4000373841694.html

My other e-bike has one of these: https://www.ebay.com/itm/3X-12-80V-Universal-Bright-Led-Strobe-Motorcycle-Headlight-Indicator-Fish-E-H1J8/254549100605
I wouldn’t pay 15 bucks for it, though. I think I paid about $3. It only has a fast strobe setting, and the optic throws a super concentrated spot. I chucked it in the lathe and sanded the lens to a matte finish to diffuse it.

That's sort of the issue. Either way, you have a buck converter involved, either built into the light or external. So you can either have one, and install simple lights that are cheaper, or choose from a fairly limited selection, especially if you're running 20S, and paying the additional cost of those units electronics. I'm more in the camp of avoiding running too many battery voltage lines between the front and back of my bike. I'm only using the HV lights up front because the cycle analyst already has a battery level voltage output built in.
 
Hey guys, not knowlingly i bought the same light as in here, plus i have the same motor... https://youtu.be/bVVs4SXMzW8
