Do these mount at factory location without drilling?

These are designed for factory mounting points — no drilling required. Test-fit before final fastening to confirm alignment with your specific bumper condition.

Are bulbs included with this kit?

Bulbs are not included. You'll need to source the correct bulb type separately and confirm fitment with your vehicle's manual before installation.

Does the switch hardwire directly into the dash?

The switch assembly is included, but wiring routing and dash integration depend on your comfort level with electrical work. Consider having a shop verify connections to factory circuits before powering on.
