If those are for the rear license plate I have them and they work good.

921’s are reverse and cargo. I see them at Auto Zone for about $20-$25. A friend has a set in his cargo. Not as bright as mine, but cargo should be ok. Def not reverse, get a good quality high output LED.

I was thinking for reverse light ... I had the 3157 version of those bulbs in my old Jeep I had and they were night and day better than OEM ... it was surprising to see that small of a light bulb for reverse light on a full size truck

I’m Leary if everything because of canbus In these Dodges. I bought Luyed from Amazon and now issues with canbus and it’s almost daylight when I back up and when I turn on my cargo lights. They’re extremely bright and in the pitch black I see a lot now.

Why are they better, do they cause any other problems and are they plug and play--
Thanks
