Will these bolt directly to my truck or do I need custom brackets?

These mount at factory rocker points — no drilling or custom fabrication. Your existing hardware works with the OEM mounting design.

Do the bulbs come with this assembly?

Bulbs are not included. Source replacements separately if your originals are burned out or damaged.

Should I clean or prep the mounting surface before installation?

Wipe the bumper contact points with a clean, dry cloth to remove dirt and debris. This ensures proper fit and prevents gaps.
