I think you’ll have to do a bit of research yourself - I could be wrong but you may not find anyone here with a definitive answer.
Look at the specs of laptops in the same range and see if any have keyboard backlights. If so, it’s possible one may fit your laptop.
Also, look for disassembly and repair guides and videos for your laptop, and when you know how to do it, remove your keyboard. There may be an empty ribbon cable socket next to the keyboard data ribbon socket. If so, this is likely to be for the backlight. You may be able to see it on some of the guides and videos.
If you find a compatible keyboard, make sure it’s the right nationality or you may find some of the keys in the wrong places.
