Do I need wiring harnesses or connectors to install these?

Wiring harness is not included. You'll need to source the appropriate connector set for your vehicle or splice into existing fog light wires if your Accent has a factory fog setup.

Will the smoke lens reduce light output noticeably?

Smoke tint does filter some light, but the 881 bulbs are engineered to compensate. You'll have a darker appearance with functional visibility—not a show-only piece.

Can I replace the 881 bulbs myself after installation?

Yes. Once the assemblies are mounted, the bulbs pull straight out from the rear of the housing for easy replacement when they burn out.
