Questions & Answers

Ask a Question
  • Do you need a conversion kit for a Subaru Legacy 2015 ? Or can I just replace the factory bulb with this bulb?

    If your 2015 Legacy has factory equipped HID system, this set of D4S bulbs fit as plug and play. 
    If it came with Halogen lights, you need to have a HID conversion kit.
