Do I need to wire this myself or does it plug into the factory harness?

It's designed for factory mounting locations with existing electrical connections. Verify your truck's brake light harness matches the connector before finalizing install — no custom wiring typically needed if you're replacing an original light.

Will this work if my original brake light is damaged or non-functional?

Yes. This is a direct replacement for the factory center brake light. As long as your truck's electrical harness is intact and power reaches the original mounting point, the LED unit will function immediately.

What's the difference between LED and the stock incandescent bulb I have now?

LED lights burn brighter, respond faster when you brake, and last significantly longer. You'll notice crisper visibility and a more modern look. The trade-off: LED is a one-time investment versus occasional bulb replacements.
