I have a 2022 Longhorn 1500 ECODiesel with the Longhorn Level 1 Equipment Group. I can not locate a setting for “steering directed lights”, just dynamic lighting. I want to mention, to avoid confusion, that from discussions I've seen on the RAM HD forums, the HD's have different DIC settings for lighting than the 1500.
Last night I decided to go out and find out firsthand what the DIC option "Dynamic Lighting" controls (I should have done this a long time ago). The steering-directed lighting feature was unaffected but the fog lamp on with the turn signal was disabled and enabled by toggling the "dynamic lighting" setting.
I can't speak for any other model, trim level, or model year outside of my 2022.
