Will this bolt directly into my factory mounting points?

Yes. This assembly uses the original brake light mounting locations — no drilling or bracket fabrication needed. Line up the housing and secure with fasteners.

Do I need to cut into the wiring harness to install this?

Your existing brake light connector will plug in. If the connector doesn't match, you may need a simple adapter harness — not included with this unit.

Does the smoked lens reduce brake light brightness?

Smoked lenses darken the output slightly, but the LED array is bright enough to meet visibility standards. If you're concerned about low-light detection, test the fitment before permanent installation.
