These are D2-connector 2A88 CANBUS 35 watt HID ballasts, from HYLUXTEK. With true OEM-grade manufacturing, these ballasts are intended to perform for years, with absolutely zero failures.
If you have a D2 OEM HID setup with a failed ballast, you can purchase one of these to get back up and running at a fraction of the cost of a new ballast from the dealer. You'll simply need to tap the positive and negative input wires into the power wires powering your original ballast.
This ballast should be used with D2 bulbs only (D2S, D2R, D2C, etc). If you have a D1 bulb, or a standard aftermarket AMP HID size such as 9006, H1, or H11, please use our AMP or D1 ballast instead.
Most ballasts these days run with digital signal processing (DSP). This allows for a much smoother and more reliable power output, faster warmup, and longer bulb life. However, most digital ballasts still use standardized computing chips to process the information. It is very cost-efficient to use standard chips off the shelf. Instead, the HYLUX uses a computing chip designed specifically for the purpose of running an HID bulb. This is known as an application-specific integrated circuit (ASIC). While this is much more expensive than a generic chip, it allows the HYLUX ballast to operate with extremely high efficiency and performance, far exceeding that of any generic ballast on the market.
The ballast is fully sealed in electrically-safe sealant material, known in the industry as potting. It's not just coated like cheaper ballasts, instead, it is filled to the brim, making the ballast completely waterproof and shockproof. The ballast will make a humming noise during operation- most assume this is bad, but actually, it is primarily a result of microscopic air pockets resonating inside, audible proof that the ballast is completely airtight.
With the OEM-grade 23kV igniter, which is also fully waterproof, this ballast will strike the bulb perfectly, every single time. It will function in even the coldest of environments, with a rated minimum operating temperature of -40 degrees.
This ballast has a CANBUS module, which is designed to provide extra resistance to the vehicle. This is required for operation in many newer vehicles, as they may otherwise shut off power to your headlights, due to the lower power consumption.
The CANBUS module also regualtes the power input, to prevent errors with PWM signals. What is that? Well, many newer vehicles use pulse-width-modulation (PWM) to drive headlights, which basically flickers standard halogen bulbs on and off very quickly, to extend bulb life and lower power consumption. It works great for traditional filament bulbs, but HIDs require constant power to run reliably. The CANBUS module smooths the input signal into a constant power supply to the ballast. It has been tested and is effective with PWM signals up to 100hZ, which is within range of PWM systems in most US-market vehicles, such as Dodge, VW, BMW, etc.
We recommend using high-quality aftermarket bulbs with this ballast, such as CNLight, or an OEM-grade bulb such as Philips or OSRAM. However, if you have any random, cheap bulb that is in working condition, this ballast will drive it perfectly.
