Night Edition LED Tail lights

[81Sprint]

Does any one know the part numbers for the LED night edition tail lights? found the regular but can't seem to find the night edition ones. Used the search already

Find a truck with them and post the request with the VIN in this thread:

Looking for a Part Number? Must provide VIN (only up to model year 2020 at this time)

I'd like to give back to the members of this forum for all of the help I've been given since I bought my HD earlier this year. I've recently gotten access to a Mopar electronic parts catalog that lets me filter by VIN. In the past I've struggled at times to figure out what part I needed when I...

Here is what I ordered for adding BSM to my night edition Big Horn, they have the black centers.
Drivers side with 2020+ BSM: 68446841AE
Passenger side with 2020+ BSM: 68446840AE

Thanks, but don't need the BSM just need the regular ones. I will try to find the VIN for a non BSM night edition truck

Here use my VIN, I have the night edition without the BSM.

Thanks for the VIN, i was able to get these ordered. Is there any changes that need to be made with ALPHA obd to make these work? I was able to get the LED headlights to work with the other thread but haven't seen anything on the tail lights.

Yes, if you currently have incandescent tail lights, you’ll need to make these changes:
CBC Features: LED Reverse Lamps Present- YES
CBC Features: LED Stop Lamps Present- YES
CBC Features: LED Rear Turn Lamps Present- YES
CBC Features: LED Tail Lamps Present- YES
CBC Config I/O Usage: Separated Lighting Brake Lamp Dropout- YES

Hey Jimmy, what is the reason for these changes I just installed the tail lights yesterday and seems to be working correctly? I will be messing with AlfaOBD so I will make the changes but I am jut curious

The LED settings turn off the PWM on those light circuits so in cold weather startups, the duty cycle isn’t low enough that the BCM shuts the circuits off, or they start to flicker, because it is looking for the resistance of halogen bulbs.
The last brake lamp dropout setting is so the turn signal operates correctly with the brake lights. Since the red brake lights are on the same LED array as the amber turn signal lights, right now, when you use the turn signal while braking, it will flash amber-red-amber-red. Changing that setting corrects it so it flashes amber-off-amber-off.

Thank you for such a detailed response!
