Backup light bulb

[Hodag Ram]

Hello all, I’m new to the forum, thanks for the add. I’m looking to replace my backup lights with LED bulbs. I have a 2018 Ram 1500 Sport with projector headlights. I bought a pair of 921 Sylvania bulbs, but the base of the ones in the truck are way larger than the 921. Is there a different bulb? The only one the parts catalog called for was the 921. ???

I have a 21' Warlock QC with projector headlights and LED taillights. I got these.
