The technical requirements have been beautifully covered by Ganges and Tron. But still the foremost thing you will require is a fresh body and absolutely tension free mind. If you are not accustomed to night driving, then you may always a carry certain anxiety at the back of your mind and this will take a toll on your body. So you need to have proper rest etc. before the journey so that your body is fresh. Then, as Ravi Sir has already said, you should take a break at the slightest hint of dizziness. Secondly, the person sitting to your left (mostly wifes, in case one is travelling with family) also has to be awake during the journey and she can discuss any topic with you during the journey. The topic is not at all important, but this chatting will keep you awake through the journey. Last but not the least, ensure that the road is safe for night driving like you are not crossing any reserve forest area or any naxal infested area. Once you venture out at night, I am sure you will start loving it.
