Product Details

SYLVANIA Basic Box focuses on OE-style replacement lighting for drivers who want a straightforward service part. This D5S.BX bulb is designed for HID headlamp systems and matches the original bulb format used in many Audi, Chevrolet, GMC, Ford, Hyundai, Kia, Jeep, and Fiat models. If you are searching for a D5S HID headlight bulb for an Audi A4 Quattro, Chevrolet Silverado 2500 HD, or Ford Transit-250 with HID headlights, this part is built for those factory-equipped applications.

The bulb uses a PK32d7 base, operates on 12 volts, and produces a clear white light output at 4150K. Because HID bulbs are not interchangeable with halogen bulbs, confirm that the vehicle is equipped with HID headlights before ordering. Part number D5S.BX is also referenced as Sylvania D5S.BX for the same application.

Installation Notes and Tips
