Raybrig never did made a big splash over here in the USA, as their products were just a little too expensive for the scene at the time.
Raybrig is the racing division of Stanley Lighting (provider of nearly all OEM Japanese car light housings).
Those of us "in the know" remember their awesome JGTC cars, and a few of us have had the luck to be able to run these housings on our cars.
I have run these on my AW11, SW20, AE86 and KP61. The light output is downright awesome and super crisp.
These housings are the ones that have a light blue tint to the front lens.
Sold in a pair. These come with the Raybrig Bulbs as well!
Sorry to gush...these things are badass.
