Do these bolt straight onto my cab without any brackets or adapters?

Yes. These mount at factory rocker points — no drilling or custom fabrication needed. Line up the bolt holes and secure.

Will I need to replace the bulbs, or do these come with them?

The headlight assemblies are included; bulbs are sold separately. Check your vehicle manual for the correct bulb type and wattage.

How do I protect the chrome finish during and after install?

Avoid touching the polished surface with bare hands — oils cause spotting. A microfiber cloth and mild soap keep the chrome clean. Avoid abrasive cleaners that dull the finish.
