Modern vehicle do have permanent dtrl. While this improves safety on the road, it might be disturbing during observations, as the target might notice the vahicle more easily.
We can fix that issue by adding the option to temporarily disable dtrl. The option will be, depending on the specific vehicle, available by light switch, in instrument panel cluster or the Sync system.
Additionally we add an option to enable the Dark Car Mode. This allowes you to turn off welcome and automatic interieur lighting as well as the central locking aknowledgement of the turn indicators.
You must not use dtrl switch of on public roads!
