Will these plug directly into my truck's factory wiring?

Yes — these connect to the existing fog light harness without modification. If your truck came with fog lights, the connectors are already there waiting.

Do the smoked lenses reduce output or throw?

Smoked lenses are designed to maintain functional light output while delivering visual tint. Real-world brightness remains strong enough for fog and low-visibility driving.

Can I run the DRL function separately from the fog light?

The LED DRL is integrated into the assembly and will operate on its own circuit — you don't need to activate the fog lights to run the daytime lights. Your truck's existing controls handle the logic.
