Do these require any wiring beyond what's included?

The switch is included, but you'll need to run power and ground from your battery or fuse box to the switch terminals. Basic 12V automotive wiring — most shops can knock it out in under an hour if you're not comfortable doing it yourself.

Will the smoke lens block too much light output?

Smoke tinting reduces output slightly compared to clear, but it's minimal and factory-quality. These are designed as functional fog lights, not just cosmetic, so you'll still get real visibility improvement in low-light conditions.

Do these mount directly to the factory bumper holes?

They use OEM-style mounting points on the front bumper. Test-fit before committing to any fasteners — verify your bumper cut-outs align with the assembly mounting tabs to confirm zero modification needed.
