I wasn't aware of the performance of the Xenons on my wife's 2012 Mazda 3 Sport deteriorating up to the point we sold it in early 2021.

I would assume as a function of use.
I.e. The brightness of 10 year old bulbs that have been on for 10k miles will be a hell of a lot brighter than 10 year old bulbs that have done 222k.
