Will these mount directly into my factory fog light openings?

Yes, these are designed for factory mounting points — no drilling or modifications needed. Line them up with your existing holes and secure with the provided fasteners.

Do I need to run new wiring, or does the switch handle everything?

The integrated switch simplifies the job, but you'll still need to run power from your battery or existing electrical system to the switch. Factory fog circuits vary — check your truck's wiring diagram to confirm tap points.

Can I return these if the fitment doesn't work out?

Contact ModSupply's support team with photos of your setup if you run into any issues. Return eligibility depends on condition and timing — they'll walk you through it.
