FAQs
What bulbs does it use?
H9 low, HB3 high and WY21W turn, per the listing photos.
Will these fit an LED low-beam Trailblazer?
No. Factory halogen low-beam models only.
Do I need to remove the front bumper to replace these headlights?
Yes, the fascia corners must come off the fender tracks to reach the headlamp fasteners.
Can I install HID or LED 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.
