  • 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.
