OEM HID Headlight Ballast — BMW & Volvo Direct Replacement

The Pro Vision Lighting™ OEM HID Headlight Ballast is a direct factory replacement for the Mitsubishi Electric W3T13271 headlight control module, as fitted to BMW 3 Series (E90/E91) and Volvo S80, V70, and XC70 vehicles from 2005 to 2012. This unit is engineered to restore reliable, flicker-free operation to your factory HID xenon headlight system.

This ballast is manufactured by Mitsubishi Electric and supplied as original equipment to both BMW and Volvo under their respective OEM part numbers. It is a universal-specification unit rated for D1S, D1R, D2S, and D2R HID globes — making it compatible with both BMW (D1S) and Volvo (D2S) factory headlight systems. Installation is 100% plug-and-play with no rewiring or coding required.

Common symptoms of a failed W3T13271 ballast include one headlight flickering, failing to ignite, or shutting off randomly after a short period of operation. On BMW vehicles, a failed ballast will typically trigger a "Check Headlight" or "Headlight Malfunction" warning on the instrument cluster. On Volvo vehicles, the same fault will illuminate the headlight warning indicator.

Note: Quantity of 1 = 1 x Ballast unit. If both headlights are affected, please add 2 to your cart.

Fault Diagnosis — Is It the Ballast or the Globe?

Before replacing the ballast, it is worth confirming the fault lies with the control module rather than the HID globe itself. The simplest test is to swap the working globe from the opposite headlight into the non-working side. If the light still fails to ignite with a known-good globe installed, the ballast is the cause of the fault and should be replaced.

If the headlight flickers briefly before shutting off, or if it takes several attempts to ignite before staying on, this is a classic sign of a failing ballast rather than a globe fault. A globe fault typically results in a complete failure to ignite from the first attempt.

Frequently Asked Questions

Will this ballast fit my BMW E90 3 Series?

Yes, provided your E90 or E91 is fitted with factory HID xenon headlights (not all variants are). Check that your original ballast carries the part number W3T13271 or 63126948180. If it does, this is the correct direct replacement.

Will this fit my Volvo S80, V70, or XC70?

Yes — the W3T13271 / 30744459 is the factory ballast for the Volvo S80, V70, and XC70 from 2006 to 2011 with factory HID headlights. The Volvo OEM part number for this unit is 30744459.

Do I need to replace both ballasts?

Unlike HID globes, ballasts do not need to be replaced in pairs. You only need to replace the unit that has failed.
