When a failed ballast leaves a xenon headlight dark, the Dorman xenon lighting ballast, part number 601-059, is a High Intensity Discharge (HID) lighting ballast designed to help restore proper headlight function. It fits many vehicles, among them the 2011-2014 Toyota Sienna, 2011-2014 Toyota Avalon and 2013-2015 Toyota Land Cruiser. See the "Vehicles it fits" section for the full list.
- Direct replacement: Designed to match the original HID ballast's fit and performance on the listed applications.
- Replaces a failed unit: Intended to take the place of an original ballast that has failed because of a voltage surge in the electrical system.
- Quality construction: Built from quality materials for dependable operation.
- Expert backing: Supported by Dorman's team of product experts in the United States and more than a century of automotive experience.
An HID ballast converts the vehicle's low-voltage supply into the high voltage needed to ignite the xenon bulb, then regulates power to keep the arc stable. Signs the ballast may need replacing include a headlight that will not light, flickers, or cuts out intermittently. A bulb or wiring fault can cause the same symptoms, so diagnose the cause before replacing the ballast. If the original ballast is the cause, this unit replaces it.

It converts the vehicle's low-voltage supply into the high voltage needed to ignite a xenon HID bulb, then regulates power to the bulb while it runs.
Will this xenon ballast fit my 2011-2014 Toyota Sienna?
Yes, the 601-059 is listed for the 2011-2014 Toyota Sienna, along with the 2011-2014 Toyota Avalon and 2013-2015 Toyota Land Cruiser. Check the "Vehicles it fits" section for your exact vehicle.
What are signs an HID ballast may need replacing?
Signs include a xenon headlight that won't light, flickers, or cuts out intermittently. A bulb or wiring fault can cause the same symptoms, so diagnose the cause before replacing the ballast.
What can cause an HID ballast to fail?
A voltage surge in the electrical system can damage an original ballast. The 601-059 is designed as a direct replacement for a ballast that has failed that way.
Is this ballast a direct replacement for the original?
Yes. It is designed to match the original HID ballast's fit and performance. HID circuits carry high voltage, so follow the vehicle service information when installing it.
