The Diode Dynamics' HID conversion kit contains everything you need to convert your factory halogen headlamps into HID, High Intensity Discharge.
In any HID kit, the ballasts are the most important component. At Diode Dynamics, we conduct extensive electrical measurement to determine which ballasts to offer. We offer two excellent options, a high-quality slim digital ballast from Precision HID, and the industry-leading ballast from HYLUX. They are both the smallest you will find, about the size of a pack of playing cards. Included are the features of automatic reverse polarity protection, EMI circuit shielding, hot restrike protection, and is fully waterproof and shockproof. It has all of the speed and arc control accuracy that comes with the new digital technology, to ensure long bulb life. While both will provide excellent results, the Precision ballast is meant to be a very good economical option, while the HYLUX ballast will provide extremely high reliability, with OEM-ballast quality.

The bulbs included with Diode Dynamics kits are CNLight bulbs. CNLight is the top manufacturer of aftermarket bulbs in the world, providing the best quality available. They are laser-aligned for easy alignment and installation, as well as long bulb life.
The bulb temperatures are rated accurately in Kelvin temperature, and have an industry-standard 2500 hours of estimated bulb life, which should outlast your vehicle.
3000K is our lowest temperature, and has a pure yellow output, which is great for use in fog lights.
4300K is a pure white output, as seen on many factory HIDs. It will not have any blue tint to its color.
6000K is our most popular color, which produces an ice white color. It has a slight hint of blue, and matches best with our LED bulbs.
8000K is our highest temperature, which produces an ice blue color.
Do not be fooled by overrated "lifetime" warranties from other manufacturers and distributors. The warranty is only as good as what the company actually replaces. Our warranty is through Diode Dynamics, LLC, so you can be assured that you will get fast and friendly service should you have any problems. In addition to the 1-year full warranty included with all Diode Dynamics products, your HID kit comes with a limited lifetime warranty. This lifetime warranty covers the ballasts and wiring for the lifetime of your HID kit.
We carry our own inventory, so no waiting for them to be shipped from overseas, or waiting on big, unreliable suppliers to ship them. They ship right from our own inventory, in St. Louis, Missouri, usually the same day you order.
Kit comes with:
- One pair CNLight HID bulbs in your choice of bulb size and color
- Two 35w super-slim ballasts (Precision or HYLUX)
- Mounting hardware for ballasts (3M mounting pads)
- Limited Lifetime warranty on electronics (ballasts and wiring)
- Full one-year warranty on all components
- Free Diode Dynamics decal
- Diode Dynamics 30-day satisfaction guarantee
- HID Relay Harness (Optional, $10) to protect your factory electronics.

Night and Day Difference! Review by Nate
Price Value Quality
The kit was very easy to install once I wrapped my head around the fact that I had to leave a plug disconnected due to the relay, which by the way is a must! Some additional pictures or a video would be helpful, not a lot out there on the web for an 05 LGT. Super bright compared to stock headlights and worth every penny. Fast shipping and excellent customer service. Don't hesitate to buy these lights if your in the market! (Posted on 3/1/13)

My lights look great! I immediately noticed much more visibility at night. The installation took no more than 45 mins, and came with easy to follow instructions.

The Superior HID's Review by Tim
Quality Price Value
I got the 6000k kit for Christmas last year. I waited till May to install it. The installation wasn't well documented but most can figure it out based on the design. Get a bit of outdoor silicon to help seal the bulb to the low beam casing.
GET THE RELAY! I had a friend install a non DD HID kit and didn't get the relay and now he's got spotty functionality from one of the bulbs.
My last car was a BMW 3 series with stock Xenon HID's. They seems brilliant compared to what I was used to. Now having experienced this kit, I am confident that this is the superior product. Thanks DD for the added safety, visibility and pretentiousness that comes with this kit. (Posted on 11/20/12)
If you're looking to upgrade the poor OEM lighting on your Legacy, this is the solution! Review by Spider96
Quality Price Value
I recently bought and installed the Diode Dyanmics 2003-2013 Legacy HID low beam 6k kit. First off, I am kicking myself repeatedly for having wait this long to upgrade the lighting on my 08 LGT. The first night I drove it I thought the headlights had burnt out. Granted, I came from an 07 STI with upgraded TSX lenses and a 6k 55w HID kit from a well known vendor on the STI forums, so I thought ALL other headlights weren't very bright, lol. I bought a pair of the best Silverstars I could find and they worked a little better but still not great. When one burned out the other day, I decided it was time to lay out a little extra $ and light up the night :) After scouring LegacyGT.com, I came to the conclusion that Diode Dynamic's kits were it only of excellent quality, but affordable as well. And their warranty was hard to beat. I placed my order late Monday night. While the site claimed that the 6k temp was out of stock, it also claimed they'd be back in stock on Sept 7th. Monday was the 10th. So I placed my order, fingers crossed. Shipping was a very reasonable $5, something I believe they refer to as Diode Delivers, or something similar. I opted for the $10 harness as well, although I feel I should mention, the site should be a little more specific as to whether or not you really require this part. I'm not sure if some cars would be fine without it and while it doesn't simplify the install in any real way (there's a transistor to mount and a few extra zip ties), I found it to help clean up the install and the HIDs light up immediately and begin their warm-up. After a few update emails throughout the week, the order arrived on Saturday morning and installed in a few hours. I took my time drilling the dust caps and took a few breaks during the install for various things, so if you really want to, you could install in an hour plus a little. Everything pieced together, the provided grommet is great and easy to push through the dust cap and allows the wires to adjust in and out as needed. Once everything was mounted up, I fired them up and they came on quickly.
I was skeptical to go with 6k for fear that the lights would be a little too blue and annoying, "ricey" for you haters, lol. I couldn't wait until night time to see how they looked, but when i went outside at 10:30 and fired them up they glowed blue for a few seconds and then turned an intense white. They completely lit up my front yard which my old lows never could.
I think Diode Dynamics should include a brief harness how-to along with the harness. I, like many others, we're confused as to why there was only one harness plug that connected to the factory harness. Maybe it's common knowledge that the passenger side be left undone, but I had to pull out the iPad and search around LGT.com before I found an answer. PROBABLY should have just looked on the site first (not sure if it's on here or not), but hindsight is 20/20. Other than that, this kit is awesome. It felt nice and solid, the lights are bright and Diode Dynamics will be getting more business from me in the near future as I upgrade more of the lighting in my car. On that note, the Diode points system is great! Make sure you sign in before you order and you get points to be used for money off future buys. The more you buy, the cheaper stuff gets later on. I forgot to sign in and my points were never added to account, even though the order still showed up under my account...a quick email later and Nick had them added to my account with an apology/confirmation response email. That's good customer service, something that has sadly become uncommon these days. Thanks again DD! (Posted on 9/16/12)
The installation of HIDs consists of three main steps, which are the same for every vehicle. The process is quite straightforward:
- -Remove factory bulbs and replace with HID bulbs
- -Connect ballast to bulb plugs
- -Mount ballast and clean up wiring
The following video shows installation on a Scion FR-S, which is very comparable to installation for most vehicles. The only tedious part for some vehicles will be accessing the bulb itself. Please check your manual, as some vehicles require the removal of the front bumper cover. Still, the installation should only take 60-90 minutes.
- - Full 1-year warranty on all products
- - No waiting: we usually send new items out with a return label (US customers only)
You will get quick help from our trained staff for any issues.
All HID ballasts also carry a lifetime warranty.
