Will these bolt directly into the factory holes?

Yes, these mount at the original bumper positions. No drilling or modification needed — bolt straight into existing attachment points.

Do these lights come with bulbs?

The lights themselves are included. Verify your bulb type and wattage against your original lights before ordering replacement bulbs separately.

Are there any gaskets or seals included?

Not confirmed with this set. Inspect the mounting area for existing gaskets or seals before installation — you may reuse what's there or source new ones if needed.
