Will these bolt straight into my factory fog light holes?

Yes. These mount at the factory fog light points—no drilling, cutting, or bracket fabrication. Remove the old housings and install these in their place using the existing fastener points.

Do I need to modify my wiring or add a relay?

No modifications required. These plug directly into the factory fog light connectors. Your truck's existing electrical system will handle the LED draw without a harness upgrade.

Will the smoked finish fade or peel over time?

The smoked tint is integrated into the lens itself during manufacturing, not applied as a coating. It's permanent and won't peel, flake, or degrade from UV exposure or weathering.
