NOTE: These ballasts are refurbished / factory take-offs. They are authentic OEM parts, but the actual condition may vary relative to what's shown in the photos. Full functionality, performance, and warranty are all guaranteed.

Tried and True: The Denso slim ballasts have been around for years but as the saying goes; "if it ain't broke, don't fix it" as there's virtually no room for improvement.

OEM Kinda Guy: Great choice for those "OEM or nothin!" kind of guys who need a set of ballasts to power their new D2S-based projector retrofit. The Denso's are found under the hood of many modern Toyota, Lexus, Mazda, and Porsche vehicles as part of the original-equipment HID system - if these big names trust them, so should you.

But Wait: With all this good, what about the bad? Well, OEM ballasts are designed to be mounted completely or partially inside of a headlight housing, so their shell is not naturally water-proof, and if they get wet, their warranty will be void. NOTE: If you waterproof them yourself, the warranty is VOID!

Good Deal: These like-new ballasts are cleaned, tested and re-certified in house to ensure perfection functionality. We offer them for $200/pair including the custom outputs, compare to dealer list at around $450 each!
