Do these bolt straight into the factory fog light slots?

Yes. These are designed for the factory mounting points on the Cascadia bumper. No drilling or modifications needed — they bolt in where the originals sit.

Will I need to pull the bumper to install these?

Access from behind the bumper is typically easier, but test-fit first. Some operators swap them without full removal depending on your tool setup and working space.

Are bulbs included, or do I reuse the originals?

Bulbs are not included. You'll use your existing bulbs — confirm the socket type with your current fog light before ordering if you're replacing damaged units.
