The dash illumination barely changes with the lights on or off in my car. That plus the fact the there are daytime running lights on the front illuminating things a little means that I often forget to turn my lights before setting off (usually realise after a few seconds).
The daytime running lights will mean there will be lights on the front of the car, but non on the rear.
