2011–2014 Chrysler 300 to 2015–2020 Tail Light Conversion Guide
The 2011–2014 Chrysler 300 features a distinctive rear styling that was refreshed for the 2015 model year, introducing redesigned tail lights and a revised rear bumper. Many owners of earlier Chrysler 300 models choose to upgrade to the newer 2015–2020 OEM tail lights to give their vehicle a more modern factory appearance.
One of the most common questions is:
Can you install 2015–2020 Chrysler 300 tail lights on a 2011–2014 Chrysler 300?
The answer is yes, but the conversion requires more than simply replacing the tail lights.
Although the 2015–2020 OEM tail lights use the same overall mounting location, they have a different shape and wiring configuration than the earlier models. A tail light conversion harness is required to adapt the factory wiring, and the 2015–2020 rear bumper must also be installed for the tail lights to fit properly.
This guide explains why the conversion requires additional components, how the plug-and-play tail light conversion harness works, and what you need before beginning the installation.
Why Upgrade to 2015–2020 Tail Lights?
The updated 2015–2020 Chrysler 300 tail lights give the vehicle a cleaner, more modern appearance while maintaining an OEM look.
Many owners perform this conversion because it offers:
- Updated factory styling
- Newer OEM appearance
- Factory-quality fitment
- Modern rear-end design
- Plug-and-play electrical installation
- No permanent wiring modifications
The conversion is a popular way to refresh the appearance of the earlier Chrysler 300 without sacrificing OEM quality.
Why Aren't the New Tail Lights Plug and Play?
Although the newer tail lights fit the later Chrysler 300 body, the electrical systems differ between the 2011–2014 and 2015–2020 models.
The factory wiring layouts are different, meaning the newer tail lights cannot be connected directly to the earlier vehicle wiring.
A vehicle-specific tail light conversion harness adapts the factory wiring so the newer tail lights operate correctly while preserving the original wiring.
What Does the Tail Light Conversion Harness Do?
A plug-and-play tail light conversion harness connects the 2011–2014 Chrysler 300 factory wiring to the 2015–2020 OEM tail lights.
Rather than modifying the factory wiring, the harness corrects the wiring layout so the newer tail lights function properly.
The harness is designed to:
- Adapt the factory connectors
- Correct the wiring configuration
- Preserve the factory wiring
- Eliminate cutting and splicing
- Support proper operation of the 2015–2020 tail lights
Because the harness is engineered specifically for this conversion, installation is clean, dependable, and fully reversible.
Why the 2015–2020 Rear Bumper Is Required
One of the most important parts of this conversion is the rear bumper.
The 2015–2020 Chrysler 300 tail lights have a slightly different outer shape than the 2011–2014 tail lights.
Because of this design change:
- The newer tail lights will not properly fit the 2011–2014 rear bumper
- The 2015–2020 rear bumper must be installed
- The later bumper provides the proper contour and opening for the newer tail light assemblies
This requirement is mechanical rather than electrical, making the bumper an essential part of the conversion.

Frequently Asked Questions
Do I need to cut or splice any wires?
No. This is a true plug-and-play tail light conversion harness that connects directly to the factory wiring using OEM-style connectors.

Is programming required?
No. Installation requires no programming, coding, or modifications to the factory wiring.

Final Thoughts
Converting a 2011–2014 Chrysler 300 to the 2015–2020 OEM tail light style is one of the most effective ways to modernize the rear appearance of the vehicle while maintaining an OEM look. Because the later tail lights use a different wiring configuration and slightly different housing shape, the conversion requires both a vehicle-specific tail light conversion harness and the 2015–2020 rear bumper for proper electrical operation and physical fitment.
With plug-and-play installation, OEM-style connectors, factory-quality wiring, no cutting or splicing, and a fully reversible design, this conversion harness provides a dependable OEM-style solution for upgrading your Chrysler 300 to the newer 2015–2020 factory tail lights.
