Do these plug directly into the factory locations, or do I need to run new wiring?

These mount at factory fog light points. The integrated switch taps into your existing electrical — no separate harness needed. You'll want to verify clearance and power routing before final installation.

Are the bulbs really included, or do I need to buy them separately?

H11 bulbs ship with the kit. If you want to swap them later for LED or a different color temp, they're standard H11 size — easy swap.

Can I return these if they don't fit?

Test-fit before committing fasteners. Mounting method is designed for factory alignment, but physical verification on your vehicle is always the safest move before you're locked in.
