Pretty sure that won't affect the warranty, if you were really worried just swap the originals back in if you need to take the bike to the dealer. I'd just get it out of the way and change them now, the stock headlight really isn't very good.
can you suggest a good LED headlight model?
I can recommend a JW Speaker 8691, but it’s a lot of work adapting/installing.
The 5.75” doesn’t put out as much Lum’s as their 7” but I had enough difficulties with the smaller one.
I’m quite pleased with the results.
Not sure of its legality in your country.

Sadly, they're not.
As bike is homologated with halogen lights, replacing them with LED is illegal unless you pass again homologation chain (which is pretty expensive, more than 500€/$)
More on that, cops are really really strict and severe with bikers so any not-100%-legal component will be sanctioned.
I know this is kinda stupid, especially for headlights as LED ones are brighter, consume less power, generate less heat, more eco-friendly etc.. but that is.
now I'm seeking for best effort choice among halogen lights providing whiter light rather than ugly stock yellowish one.
