Product Overview
Some owners arrive here after scraping the lower bumper on a driveway or damaging an old diffuser. Many are simply looking for the part that makes the Q50 rear end look lower and more finished, especially at night when the center LED is visible.
The add-on diffuser mounts below the rear bumper and provides the styling fins and wired center lamp shown. It is not the factory bumper cover, a structural crash part, or a substitute for the vehicle’s required main brake lamps.
Confirm 2018-2023 sedan bumper, trim and exhaust layout, diffuser shape, gloss finish, lamp connector, wire functions, mounting holes, and included hardware. Test the LED before drilling or final assembly.
This is an aftermarket gloss-black diffuser with an integrated LED light, not a factory bumper. Exhaust tips, rear sensors, side extensions, and the LED wiring route should be checked before final installation.

Frequently Asked Questions
Q: Does this replace the main tail lights? A: No. The center LED is an added light and the original lamps must remain functional.
Q: Is drilling required? A: Many add-on diffusers require holes; verify the hardware and instructions before starting.
Q: Will it fit a 2017 Q50? A: No 2017 fit is promised because the rear bumper design changed for 2018.
Q: Is this an original-equipment part? A: No. This is a new aftermarket product. Brand names and part numbers are used only to identify compatible applications.
