LED fog lights not working

[Mjolive]

I have a 2017 sport. I bought some Auxbeam F16 plus bulbs for the low beams and fogs . The low beams work fine. But the fogs when installed the passenger would work but the driver side would come on for a second when turned on but turn back off. Swapped bulbs from driver to passenger and the exact same results. Put the incandescents back in and they work fine. Any ideas as to why they are not working?

You'll either need canbus adapters or get alphaobd (Google play store $50/obdlink mx $70) and enable a few things for them to work correctly

^^^ what 1500ram12 stated
If you just turn the ignition on without starting the truck, the fogs will work fine. It's the trucks bulb out detection that causes the issue.
I've used these on several types of LEDs on the notoriously picky '15 model year: https://www.diodedynamics.com/canbus-anti-flicker-module-pair-connectors.html

Isn’t the box inline the Canbus driver? Or am I mistaken?

Some have a canbus compatible driver, some have a second box that is the canbus adapter. Most, like that are just a driver.
