Do I need to remove the front bumper to install these?

These mount at factory fog light locations, so you won't need to remove the bumper. Access from inside the wheel well or from underneath works fine — check your service manual for your specific Rogue's layout.

Will the wiring harness work with my existing fog light switch?

These are designed to use your factory wiring connections. If your Rogue has fog lights from the factory, the harness plugs directly in. If it doesn't, you'll need to run wiring and may want to add a separate switch.

Can I return these if they don't fit?

Contact ModSupply customer service with photos and fitment details — they'll walk you through the return process. Keep the assembly in original condition for fastest resolution.
