Will this bolt straight to the factory mounting points without adapters?

Yes. This light mounts at the OEM locations—no brackets or adapters needed. Just align and secure using the existing fastener holes.

Do I need a wiring harness adapter, or does it plug into the factory connector?

Wiring compatibility depends on your specific year and model within that span. Test the factory connector before finalizing installation. Some may require a simple pigtail; others plug directly in. Check your vehicle's brake light circuit before committing.

Is the lens sealed against water intrusion?

Hard panel construction is weather-resistant for normal road use. For extreme off-road or high-pressure wash applications, inspect the seal periodically to ensure no moisture accumulation inside the housing.
