Will these bolt straight into my factory bumper holes?

These mount at factory points — no drilling or modification needed. Test-fit before final installation to confirm alignment with your specific bumper condition.

Do I need to remove the bumper to install these?

You'll need access to the mounting points behind the bumper. Bumper removal varies by vehicle — check your service manual for your specific model. Some DIYers do it in place; others pull the bumper for easier access.

Are the bulbs included, or do I need to source them separately?

Bulbs are not included with this assembly. You'll need to source replacement bulbs separately — verify the correct type for your application before ordering.
