Does this replace my factory brake light, or is it an add-on?

Direct replacement for the factory center third brake light. Mounts at the same location using existing holes—no drilling or fabrication required.

Will I need to tap into my existing wiring, or does this connect to the factory harness?

Mounting method and electrical integration details are not specified in the product information. Verify connection points and wiring compatibility with your vehicle's brake light circuit before installation.

Can I return this if it doesn't fit or work with my setup?

Review the return policy during checkout. Before purchasing, confirm the assembly is compatible with your specific vehicle year and that your brake light circuit can support LED power draw.
