Cool thank you. Need to do some more research.  |
It's actually just 2 bulbs period! HID stands for high-intensity-discharge which means that in each bulb tube there's an inert gas (in our case Xenon) that facilitates an electric arc being created between two tungsten electrodes. I believe there are some salts inside the tube that evaporate because of the electric arc and create plasma to increase light intensity and output. The way bi-xenon's work, there's a shutter in the projector housing that covers half of the projector. If you ever notice a slight clunking sound when you flash your high beams, that's the shutter opening up to allow the entire projector to shine the light through.
Also a correction, I dug back through my email order confirmations and realized I actually ordered mine through PowerBulbs:
