Do these mount at factory rocker points without drilling?

Yes. These use your truck's original fog light mounting locations. No modification to the bumper or body panels needed—bolt straight in.

What do I need to do to wire these into my truck?

The switch and harness are included. You'll need to run power from your battery to the switch, then from the switch to the fog lights. Basic automotive wiring knowledge or a shop can handle this in under an hour. Refer to your truck's service manual for factory electrical integration points.

Do the bulbs come installed?

The assemblies come ready to mount. Verify bulb type and wattage against your truck's specs before powering on, and confirm they're seated properly in the sockets before final installation.
