Will these fit into my factory bumper marker light openings?

Yes, these are designed as direct replacements for the OEM front bumper side markers. They mount into the same factory locations without modification.

Do I need to remove the entire bumper to install them?

No. You can access and swap the marker lights from behind the bumper fascia on most setups — no full removal necessary. Work from inside the engine bay or wheel well depending on your access.

Are these just smoked lenses or complete housings?

These are complete marker light units with the smoke finish built in. They're ready to install as-is — no additional tinting, painting, or modification needed.
