35W / D2S: Denso Slim

Waterproofed Lead Time: Please note that because these ballasts are hand-built to order, this may take up to an additional 8-10 business days to ship. 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. You can protect your investment with our optional OEM Ballast Potting Service, which makes their electronics impenetrable to moisture damage. 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!
