Do these use factory wiring or do I need to tap into my own?

These come with a complete harness and switch — no splicing required. Run the harness along your existing loom and mount the switch on your dashboard or steering column.

Are these sealed against moisture and condensation?

Fog lights see more exposure than regular housings. Once installed, inspect the gasket seal at your first maintenance check and reseal if needed to prevent internal fogging.

Will the smoke tint affect light output in bad weather?

Smoke reduces brightness slightly compared to clear lenses — acceptable for daytime or light rain use. For heavy fog or night driving, consider clear versions if visibility becomes an issue.
