For trail running, the consensus seems to absolutely be - Petzl headlamps. They are light, have automatic reactive lighting technology, which adjusts the beam based on sensors, the beam shape, and color of light is perfect for running at night. You should look up - here best headlamp review with one of the newer and the older one which works well too. For street running, seeing obstacles in front of you clearly is not so important as it is on the trail, and many headlamps will work for you.
