A lamp or a flashlight?

Imagine that you have to go somewhere at night on a road that has no lights on it.  You will need to take a source of light with you and there are two available.  One is a flashlight and the other is an oil lamp.  The flashlight has fresh batteries and you can see a long distance by its light.  The lamp only gives off enough light to illuminate the area immediately around you.  Which one would you choose?

This question is a no-brainer.  With the flashlight you could see a long way ahead and know what to expect as you travel.  You wouldn’t be surprised by unexpected obstacles.  When you use a lamp only the area immediately around is illuminated and you have no idea what lies further ahead.  If there are obstacles you won’t know about them until you reach them.
