I have a 2023 Ram 1500 Bighorn and am in the process of switching to led bulbs. The owners manual calls out 7440 (single filament) for the tail light/brake light however the bulbs installed are 7443 (double filament). It appears you loose the tail light function if you use 7440 led bulbs as directed in the owners manual.
Has anyone had the same experience with this and can provide assistance?
