These bulbs are designed to mimic the filament location of the low beam, and then have a small solenoid which moves the arc into a position to illuminate as a high beam. This is controlled with the included BiXenon splitter.
The bulbs included with Diode Dynamics kits are CNLight bulbs, which are widely regarded as the most dependable and reliable aftermarket bulbs on the market. Just like the HYLUX ballasts, you will see other companies offering these same bulbs under their own brand name. They provide superior life and color attenuation when compared to generic HID bulbs, like those found in most cheaper kits on the market. With these bulbs you won't have any issue with bulbs not matching in color, or flickering, which is common in cheaper bulbs. The one-piece ceramic base design prevents any issues with separation over time, making the entire bulb extremely reliable.
6000K is probably the most popular color, which produces an ice white color. It matches best with most LEDs.
Until recently, all dual-filament bulbs required bulky wiring harness. Diode Dynamics has developed BiXenon splitters, which effectively and reliably split the high and low beam power signal, powering both the ballast, and activating the high beam function. This is a much simpler and more reliable way to power BiXenon bulbs.
The ballasts are the most important component of an HID kit, as they handle the critical and sensitive control of power. After years of providing midrange ballasts, Diode Dynamics identified a company called HYLUXTEK in 2012 as the very best manufacturer in the industry. Their newest ballast, the 2A88 slim, is simply the best aftermarket ballast on the market, and was jointly developed with Philips. These days, others have caught on- you will see other high-end retailers carrying this same ballast, usually under their own brand name, for a much higher cost.
Most digital HID ballasts on the market still use generic integrated circuits, which are the cheapest option. They work OK, but when you need maximum quality and efficiency from an electronic component, you need a new computer chip designed specifically for the job. This is known as an Application-Specific Integrated Circuit (ASIC). These ballasts use full ASIC chips for maximum efficiency and brightness, and extremely stable operation. To prevent counterfeiting, HYLUX has even included a fully-sealed transparent window in the ballast, showing the ASIC inside.
These ballasts are fully potted, or filled with epoxy, which makes them fully waterproof and shockproof. This material is expensive, so most ballasts on the market are only given a coating, or a partial fill. HYLUX ballasts are completely filled to the top, sparing no expense to ensure longevity. If you take off the back cover on this ballast, you'll see what we mean!

I was a little skeptical at first never having converted my headlights to HID before, but I must say, with the supplied instructions, this was a breeze. I had it complete within a couple of hours because I am meticulous and wanted a factory look to the wiring. I took the time to hide everything and it looks awesome. The lights are really bright compared to factory. Very happy. Really fast shipping too.
