The 2019-2024 RAM 1500 (fifth generation) came with either factory halogen or factory LED tail lights, depending on trim and package. Many owners with halogen trucks want the OEM LED tail lights for the factory look.
Can you install OEM LED tail lights on a 2019-2024 RAM 1500 that came with halogen tail lights? Yes. But swapping the tail lights alone is not enough. The LED tail lights bolt on, but the wiring is different. A conversion harness adapts the factory wiring so the LED tail lights work without cutting or splicing.
TAILLIGHTS NOT INCLUDED. The harness kit is one left and one right harness only.
Quick Answer
- Halogen and LED tail lights on this truck use different wiring.
- A plug and play harness connects the factory halogen wiring to the OEM LED tail lights.
- It is designed to help prevent hyperflash, bulb out errors and lighting warnings.
- It fits trucks that came with factory halogen tail lights only. It does not fit the RAM 1500 Classic.
- KVS sells this harness: RAM 1500 Halogen to LED Tail Light Adapter Harness.
Why Aren't LED Tail Lights Plug and Play?
The LED tail lights mount to the truck, but the electrical systems are different. Factory halogen and factory LED tail lights use different wiring layouts. Without the right harness, the LED tail lights are not designed to work on the halogen wiring.
A vehicle specific harness bridges that difference and leaves the truck's original wiring alone. For a general explanation, see Can I Upgrade My Factory Halogen Taillights to OEM LED Taillights?
What the Conversion Harness Does
The harness plugs into the factory halogen connectors on one end and the OEM LED tail lights on the other. It is designed to:
- Adapt the factory connectors
- Correct the wiring layout
- Keep the factory wiring intact
- Remove the need for cutting and splicing
Because nothing is cut, you can go back to the original tail lights later if you need to.
Hyperflash and Lighting Errors
A common worry with halogen to LED swaps is hyperflash, bulb out messages or other lighting warnings. This harness is designed to help prevent hyperflash, errors and lighting malfunction warnings. To learn why hyperflash happens, read What Causes Hyperflash After Installing LED Lights?
