Do these bolt directly to my CR-V or do I need to drill holes?

These mount at factory rocker points with no drilling needed. If your vehicle has existing fog light holes, these bolt straight in. If not, you'll need to verify mounting location before final installation.

Are the bulbs included with these fog lights?

Bulbs are not included. You'll need to source the correct replacement bulbs for your model year and plug them into the assembly.

Can I paint or modify the chrome bezel?

The chrome bezel trim is integrated into the assembly. If you want a different finish, you can remove and refinish it separately before installation, but test-fit first to confirm fitment after any modification.
