FAQs
Will these fit an STS with HID?
No. These are halogen lamps; see our HID version for xenon cars.
Do they fit the STS-V?
No, per the listing.
Do I need to remove the front bumper to replace these headlights?
Yes. The STS front fascia has to come off to reach the three headlamp bolts.
What bulbs do these use?
H11 low beam, 9005/HB3 high beam and T10 marker, all included per the listing diagram.
Can I install LED or HID kits?
Yes. This is a halogen housing, so a plug-in LED or HID kit in your factory bulb size can be used. Aim the headlights afterward.
