Do I need any additional wiring or connectors?

The switch plugs into factory locations — your vehicle's wiring harness will accept it. You may need to run a power line from the battery to the switch depending on your existing harness condition, so have a wiring diagram for your year handy during install.

Will these fit without modifying my bumper?

These mount at factory points with the integrated bezel — no cutting or drilling required. Test-fit the assembly before final tightening to confirm alignment with your bumper opening.

What if one bulb burns out after purchase?

H11 bulbs are standard automotive replacements and widely available. Keep a spare in your vehicle for roadside replacement — they twist out and install in seconds.
