HID bulbs need a ballast in order for them to work, the bulbs here are only for replacement HID bulbs, not a new install. Only for use with an HID ballast. Do not order if this is not to replace an existing true HID bulb.
Here you can find replacement HID bulbs for Larsen Lights work lights, and most OEM HID bulbs can be found here for less than OEM dealer price.
Your JD or CaseIH & more can be replaced with bulbs from Larsen Lights for less than that $200 price tag....
