Do these guards block my tail light visibility?

No. The mesh pattern is designed to let light pass through clearly while protecting the lens behind it. Your brake and turn signals will function normally.

What hardware do I need to install them?

These bolt to your factory tail light mounting points, so you're using existing holes. Check that your truck's fasteners are in good shape before install—you may need new bolts depending on their condition.

Can I paint these to match a custom color?

Yes. The black finish can be sanded and primed if you want a different color. Prep with 220-grit or higher, prime, and paint with standard automotive finishes.
