Will these work with the factory wiring harness?

Yes—these mount at the OEM anchor points and use your existing electrical connections. No rewiring or splicing needed.

Do the smoked lenses still light up bright enough to be seen?

Smoked lenses reduce light output slightly but meet safety visibility standards. They still function as marker and side lights; you'll see the orange glow through the smoke.

What if my bumper has sensor holes or additional cutouts?

These are direct replacements for the marker light openings only. If your bumper has extra sensor or washer cutouts, they remain unaffected—these lights don't cover or fill those areas.
