Will this work with my factory wiring harness?

Yes — this mounts at factory points and connects to your existing brake light circuit. No rewiring required.

Does the red housing need any prep before installation?

The housing arrives ready to install. Clean the mounting surface on your vehicle before securing to ensure a solid fit.

What if the light doesn't illuminate after I install it?

Double-check that the connector is fully seated on your brake light wire. If still dark, the bulb or LED element may need verification — test with a multimeter or contact support for a replacement.
