Products Description

Denso Koito OEM D4 HID Xenon Ballast DDLT003 (Pack of 1)

BRAND NEW DENSO KOITO OEM HID Replacement Ballast. Very slim design for an easier fit, Denso Koito HID D4 ballast is Widely used on many car manufacturers including Toyota and Lexus as the factory OEM ballast. HID ballast works to restore proper operation of the headlight of the vehicle by regulating the voltage coming out from the vehicle. This assures the overall performance of the HID bulbs.
At HID Concept, we always recommend replacing the bulbs in pairs. With that in mind, you may consider replacing the ballast in pairs as well. When one ballast goes bad, it is more likely that the other ballast will soon not function properly.

Questions & Answers

Ask a Question
  • Hello, I believe this will fit a 2008 Lexus IS250 but just wanna confirm. Am I correct or no?

    This ballast works for IS250 as it's the same DDLT-003 as your Lexus has.  One thing you need to confirm, is if a ballast with 7 inch long cable is sufficient for your installation need as some mechanics/individuals find the length of cable to be too tight. 

  • Hi, will this be a perfect fit plug&play for a V-6 Toyota Venza 2010. OEM part no. 85967-06020.. Thanks

    Yes, it is the compatible ballast module for your vehicle. 
    One thing you should check though, is to ensure that our ballast with 7"inch long cable would be long enough for your need. 

  • can use it in ford explorerer 2014 light number 9005

    This is an OEM ballast for Lexus, Toyota, etc.. not for halogen bulbs. 
    If you are looking for a HID conversion kit, we do have kit for 9005 size.
