Do these mount at the factory corner light position with no drilling?

Yes. These use clip-on mounts designed to sit in the original corner light location. No drilling, modification, or adapters needed.

Are the bulbs already installed?

Bulbs come pre-installed and ready to use. You won't need to source or fit any bulbs yourself before or after install.

What prep do I need to do before installation?

Clean the corner light mounting area to remove any dust or debris. Test-fit before fully seating the clips to make sure they align with your vehicle's body lines.
