I have a 2022 Suzuki GSX-R 125 so I can say it's really new. It's not supposed to have dimming lights this early, am I right? How can I fix this? Can someone please, if you have already tried tinkering with the tech particularly in the headlights, i would love to learn from you.
 
On a 2022, dim lights usually mean a weak battery or charging issue. You can check its voltage while running.. It should be 13.5 to 14.5V. If not, you should check on the regulator or wiring.
 
Agree with @Dayam0nd there. if it's not the battery then it could be a loose connection at the headlight itself, or even an issue with the voltage regulator. did you notice any other electrical issues, like slow starting or other lights flickering?

just wanna say that it's not normal for a 2022 model, definitely a fault
on a bike that new, I'd immediately suspect either a charging system problem (alternator/stator, regulator/rectifier) or a loose/corroded connection somewhere. Don't let it go, it could get worse
 
That's really unusual for a 2022 model. I'd recommend checking the alternator, stator, regulator, and all the connections as soon as possible to prevent any bigger issues down the line.
