Do these connect to my factory wiring or do I need to rewire?

The integrated switch handles the electrical connection. Check your vehicle's existing fog light harness before installation — some models have a pre-wired connector ready to go, others may need basic wiring work.

Will the smoke lens affect brightness or visibility?

Smoke lens reduces glare and improves nighttime visibility on oncoming traffic. Light output remains adequate for standard fog conditions — they're not replacements for headlights.

Are the bulbs replaceable once installed?

Yes. H11 is a standard bulb type available at any auto parts store. Access and swap time depends on your specific model year — test-fit the assembly first to confirm clearance.
