Do these mount at the factory bolt points?

Yes, these are designed for factory mounting points — no drilling or fabrication needed. You'll bolt them where the originals sit.

Will I need to pull the bumper off to install these?

Access depends on your truck's year and configuration. Most installations require bumper removal or partial removal for full access to the mounting hardware inside the fender.

Are the bulbs and wiring harness included?

The tail light housings are included. Verify bulb and harness compatibility with your truck's model year before purchase — aftermarket tail lights sometimes require separate bulb upgrades or harness adapters.
