Does this require any modification to my vehicle's wiring harness?

No. This assembly connects to your factory third brake light connector — just unplug the old unit and snap this one in. Your existing wiring handles the LED power draw without any changes.

Will this fit if I'm replacing an incandescent third brake light?

Yes. The mounting points are identical, so it bolts up exactly where your original sits. The LED unit draws less power than incandescent, so your electrical system won't strain.

What if the unit arrives damaged or doesn't light up?

Contact our support team with photos — we handle replacements and returns within our standard window. Keep your original unit and packaging until the replacement arrives.
