Do these lights use the factory mounting holes?

Yes. These mount directly at the factory fog light locations—no drilling or bracket fabrication needed. Use the stock fastener points for a clean install.

Do the bulbs come with these lights?

Bulbs are not included. You'll need to source the correct bulb type separately and install them into the housings before mounting.

Can I wire this switch into the factory location?

The switch mounts independently and wires directly into your vehicle's electrical system. Factory dash integration is possible but requires running wire through the interior—test fit the switch location before committing to permanent routing.
