It is best practice to minimize the use of interior lights while you are on the road, not just for your own safety, but also for the safety of other drivers on the road. And if necessary to use the lights, use the map lights at the front over the cabin lights, and have your passenger control this while you continue to focus on the road. As the driver, your main responsibility is to stay focused on the road, not be looking around in your car or doing other tasks. Just drive or let someone else drive.
