Do these plug directly into my existing wiring, or do I need adapters?

These use factory mounting points and standard connectors. You're unplugging the old units and plugging in the new ones—no adapters or rewiring needed.

Will the smoke tint reduce how much light reaches the road?

The smoked lens darkens appearance but doesn't significantly compromise output. Light passes through the tinted lens at full function. If you're in heavy fog or low-visibility conditions regularly, test them before committing.
