These are AMP-connector 2A88 CANBUS 35w HID ballasts, from HYLUXTEK. With true OEM-grade manufacturing, these ballasts are intended to perform for years, with absolutely zero failures.

If you have an HID kit with a failed ballast, you can purchase a pair of these and swap it out. The AMP connectors and 9006 size power input will fit standard HID kit wires. If you are looking for a ballast to replace an OEM HID setup, please view our D2 or D1 style ballasts.

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.

  1. Replacement ballast under warranty. Review by Helas

    One of the ballasts on my DD HID Kit for a 2012 Subaru Legacy failed. DD replaced the failed ballast with one of these for my. The replacement works as advertised. I hope it lasts longer than the last one. (Posted on 3/14/16)

  2. Finally a quality product sold by a company that you can actually talk to Review by Sferrari

    Went trough over $200 in ballasts that either didn't work well or didn't work at all. The companies that sold these products gave a "lifetime warranty" but we're nowhere to be found when their product didn't function.
    Diode Dynamics is a class act and provide quality products. They will be my 100% go to for HID lighting products from this point forward. I highly recommend l. (Posted on 1/22/16)

  3. Ballast Replacement Review by Dwayne

    I recently had a ballast go out. Because this is a daily driver, I didn't want to tear the car apart and wait for the new part to come in. I sent an e-mail on Sunday explaining that I would like a replacement so I could just swap them out at the same time. On Monday I got an e-mail back that the new one would be shipped with a RMA. I had them on Thursday of the same week. Outstanding customer service. (Posted on 11/11/15)

  4. Fantastic Product Review by Zac

    This ballast was included with the kit I ordered for my 2014 GMC Sierra. They appear to be very well built and are heavy for their size. The Hylux chip can be seen through the rear window of the ballast. The ballasts are small and because of this are easy to install in different location in the vehicle. Also included with the ballasts are squares of 3M double sided adhesive. Its nice to see 3M in the box as other cheaper adhesives don't hold as well. All the connections that should be are weather pack type connections and appear to be well made. Don't hesitate to go with Hylux if you are looking at HID's. They are on par or better that what I have used in the past. and the customer service at DD cannot be beat. (Posted on 7/18/15)

  5. Great Ballast! Review by 417FahrenheitGTi

    Very tough and easy to place. Not a big unit so its easy to hide in tight spaces. Definatly looks very well crafted. Will be buying these for all vehicles I have and get in future if vehicle doesn't have stock HIDs. (Posted on 12/8/14)
