FAQs

Will these fit a Trailblazer LS?
No. LS uses a halogen-signal lamp.

Will these fit a 2023 Trailblazer?
No. 2024 refresh only.

Do I need to remove the front bumper to replace these headlights?
Yes. The front bumper fascia has to come off to reach the headlamp bolts. Plan on 1-2 hours with a helper.

Can I install HID or LED kits?
Not applicable. The low and high beams are built-in factory LED; there is no replaceable headlight bulb for an LED or HID kit.
