Ah never heard about those
They're pretty uncommon. Xenon is a pain for most companies; it doesn't like fast reheat to flash the bulbs, ballasts are expensive, et cetera. So the luxury cars introduced Xenon lights (yes, Ruby, I know, shhhh). Before the mainstream lines followed up, projectors suddenly started catching on, and they blow reflectors out of the water. So the luxury cars took those, xenon reflectors died after only about 5-6 years, and now projectors are expanding to take over the mainstream car market too, with 6 years behind them.
