Will this fit directly in place of my factory brake light?

Yes. It mounts at the factory center position using OEM fastener holes — no drilling or brackets required. Test-fit before final tightening to ensure alignment.

Do I need to replace the wiring harness?

The assembly connects to your existing brake light circuit. If your factory connector is damaged or corroded, have it inspected before installation to avoid electrical issues.

How long do LED brake lights typically last?

LED arrays outlast halogen by thousands of hours. Exact lifespan depends on your driving habits and climate, but they're engineered to handle repeated brake cycles without dimming.
