Will this bolt straight into my Rogue without any modification?

Yes. It mounts at the factory attachment points with no drilling or bracket work needed. You may need to disconnect and reconnect the factory harness connector depending on your year.

Do I need to prep or paint this before installation?

The assembly arrives ready to install. If you prefer a custom finish, standard automotive paint and primer work with the hard panel housing.

What bulb does this use?

This assembly is designed for H11 halogen bulbs, the standard for this generation Rogue. You can source bulbs separately or reuse your existing ones if they're still good.
