|Xenon incandescent headlamp.|
eBay is full of "xenon headlamps" promoted as if they were the very expensive xenon short-arc headlamps popular in very expensive brands of car and unpopular with everyone else because they cause a lot of glare. But these inexpensive "xenon" lamps are just ordinary incandescent bulbs that are, possibly, filled with xenon gas (which is legitimately used for this purpose, it's just not the same thing as an arc discharge lamp).
These type of fake arc lamp is often wrapped in blue film to make the yellow incandescent light look more like the bright blue/white light from a true arc light.
