Product Details

SYLVANIA Basic Box focuses on OE-style replacement lighting for drivers who need a factory-correct bulb rather than an aftermarket conversion. The D4R.BX is engineered for HID-equipped vehicles only and is built to match the electrical and physical requirements of the original headlamp system. Use this bulb when replacing a failed HID capsule in a Subaru Forester, Toyota Avalon, or Toyota Prius that specifies D4R fitment.

This part cross-references Sylvania D4R.BX for the same application.
