Or more like "headlight cats", specifically Hello Kitty H4 bulbs. What'll they think of next?
Still, this is a lot more words than I originally thought I could come up with for Hello Kitty headlight bulbs, the existence of which may very well be a sign that the end times are upon us.
But you usually only so those on expensive...I prefer the Marchal kitty, myself.
But it seems like the kind of thing that would be destined for a collector's shelf, not an automobile on the road.
From what I've been able to piece together from the web archive, they were offered in the early 2000s. And from what I've seen of Japanese culture, I don't doubt if when they were a current product people bought them and installed them in their cars. But now it's certainly more of a collectible (though maybe not; it doesn't look like anyone's bidding).
