Will this bolt directly to my factory mounting points?

Yes. This unit uses the same mounting holes as the OEM 3rd brake light—no drilling or welding. Bolt it in with the fasteners you remove from the old light.

Do I need to run new wiring or modify the electrical harness?

The assembly plugs into your existing wiring connector. If your truck's harness is still stock, you're ready to go. If you've swapped electrical components before, test-fit and verify polarity before final installation.

What's the difference between this LED unit and the incandescent version?

LED lights up faster and runs cooler than traditional bulbs, which means better visibility in heavy braking and longer-lasting performance. The housing is the same shape and black finish as your factory light—it's a direct swap with a durability upgrade.
