I’m assuming the question here is how to turn off the accent/signature lighting and not the actual headlights?
At least for me, I haven’t been able to figure that out either.
Daytime running lights (DRL) on my 2024 1500 Limited are just the headlights. I can enable/disable DRL in the vehicle settings menu.
In my experience, turning the light switch to off doesn’t turn off the accent/signature lighting.
In my 2022 Grand Jeep Cherokee I can turn off the accent lighting in the vehicle settings menu. That option does not exist on my RAM.
The best I’ve found for those Christmas lights drive throughs is to turn on the parking lights, which for me turns off the accent lights and gives off less light than having the lights switched completely off.
