Of course. I was referring to the comment above suggesting that they might be a $2000 factory option. I think it would be less than or around $1000 as a standalone option, although realistically, it should only be $500 or so.
Of course it's much more expensive buying the parts outright... However, each multireflector headlight only costs around $250-$300 factory, so $1800 per headlight assembly is a bit steep without the bulbs, ballasts, or controller.
