Hi, I think to replace the original halogen lights by a pair o Xenon lights.

There are several options on the market, so I get confused in deciding which one to choose.

Some friends put a Chinese model, however it could conflict with the USB radio. He reset the light when lit up.

What is the best model for our i30?

Welcome Mr Sparklle .... There are several options available to upgrade your lights I am hopeful you will get some helpful replies if you are patient

almost every aftermarket xenon kit is produced in china, even those who say are philips or philips patented.I personally have a 55w h7 kit for about 4months and i had absolutely no problems with the USB or any other electric part of the car or with the bulbs.Can't really help you with "a best model" cause all the cheap kits are basically the same thing in different package.
