Do these bolt straight into my factory fog light holes?

Yes — they're designed for factory mounting points. No drilling or custom brackets required.

Is the wiring harness and switch ready to go?

The switch comes integrated with the assembly. Route the harness through your existing fog light channels and connect to power at your battery or fuse box — standard automotive wiring.

Will the smoke lens reduce brightness too much?

Smoke tint filters incoming glare without cutting your own output significantly. LED projection is bright enough to compensate for the lens tint while driving.
