2016–2018 Honda Pilot Elite & Honda Ridgeline Black Edition to 2019–2021 OEM Full LED Headlight Conversion Guide
The 2019–2021 Honda Pilot introduced redesigned OEM Full LED headlight assemblies, giving the front end a more refined appearance while providing full LED high and low beam performance. Many owners of the 2016–2018 Honda Pilot Elite and compatible Honda Ridgeline Black Edition models choose to upgrade to these newer factory LED headlights.
One of the most common questions is:
Can you install 2019–2021 OEM Full LED headlights on a 2016–2018 Honda Pilot Elite or compatible Honda Ridgeline Black Edition?
The answer is yes, but replacing the headlights alone is not enough.
Although the newer LED headlights physically fit the vehicle, the wiring configuration differs between the original and updated headlight systems. A headlight adapter harness is required to properly adapt the factory wiring while maintaining a clean, plug-and-play installation.
This guide explains why the wiring is different, how a plug-and-play headlight adapter harness works, and what to verify before beginning your upgrade.
Why Upgrade to 2019–2021 OEM Full LED Headlights?
The 2019–2021 Honda Pilot Elite and Touring Full LED headlights are one of the most desirable factory upgrades for earlier Pilot Elite and compatible Ridgeline models.
Many owners choose this conversion because it offers:
- Modern factory appearance
- Full LED high and low beam lighting
- Improved nighttime visibility
- OEM fit and finish
- Factory-quality installation
Installing genuine OEM Full LED headlights gives your vehicle a premium appearance while maintaining Honda's original styling.
Why Aren't the 2019–2021 LED Headlights Plug and Play?
Although the OEM Full LED headlights physically mount to compatible vehicles, the electrical system differs from the earlier headlight configuration.
The original headlight wiring and connector layout are different from those used on the newer Full LED assemblies.
Without the proper headlight adapter harness, the newer headlights are not designed to operate correctly with the factory wiring.
A vehicle-specific adapter harness bridges these electrical differences while preserving the original wiring.
What Does the Headlight Adapter Harness Do?
A plug-and-play headlight adapter harness connects the factory wiring to the 2019–2021 OEM Honda Pilot Elite/Touring Full LED headlight assemblies.
Rather than modifying the factory wiring, the harness adapts the electrical connections so the newer headlights operate properly with the original electrical system.
Depending on the application, the harness is designed to:
- Adapt the factory connectors
- Correct the wiring layout
- Preserve the factory wiring
- Eliminate cutting and splicing
- Support proper OEM Full LED headlight operation
Because the harness is designed specifically for this conversion, installation is cleaner and more reliable than modifying the factory wiring yourself.

This conversion harness is designed only for specific factory lighting configurations.
For 2016–2018 Honda Pilot Elite models, the vehicle must be equipped with:

A plug-and-play headlight adapter harness eliminates permanent wiring modifications by connecting directly to the factory electrical system.
Benefits include:
- No cutting or splicing
- Factory wiring remains intact
- Cleaner installation
