Activate tail lights “in Auto” using GAP tool?
With so many activations, and so many good people looking for more, does anyone know if I can activate, or customize, tail light behavior on the Land Rover Defender (L663) using the GAP IID Tool G4 by modifying Car Configuration Files (CCF)?
With Auto being the recommended setting for automatic low beams and daytime running LEDs, I really want that mode to also activate the tail lights.
I know if/when it gets dark, and the Auto light setting changes, the trail lights come on, but I wouldn’t mind them on all the time.
If this has already been asked and answered, I wouldn’t mind a link…

I have not figured this out and have tried on the Defender. I’m sure there’s got to be a setting for it, just haven’t found it yet.
(I have another car where I coded on the taillamps / running lamps on the taillight with DRL’s and it’s great - most VAG cars you can do this do - Porsche/Audi/VW/etc).
