Here is another plan for emergency light:

• Take a piece of electric cable and a 12 volt globe. Take a flash light or brake lamp out
  if there is no spare lamp. Strip about 5 centimetre of the insulation on both ends of
  the wire. Secure one end tight on the metal outside of the globe and turn the connection
  off with insulation tape or plaster but leave the bottom contact terminal of
  the globe open.
• Connect the other point of the wire now on the positive terminal of the vehicle battery.
  The whole metal work of the vehicle is already linked on the negative terminal
  of the battery, so everywhere that you touch with the bottom terminal of the globe
  on the metal work the lamp will shine brightly. Just be carefull for short circuit with
  the electrical wire.

Here is another idea to make a lamp for your camp:

• Get two empty beer or cool drink tins
• Cut off about a quarter of the bottom side of one tin
• Make a hole in the middle of the bottom, just big enough to get a wick through and
  place the wick in the hole.
• Use string or a strip of cotton fibre material for the wick. Cut a v-shaped notch on
  the side edge.
• In the second tin, cut and bend an open tin or “window” out. The two flaps on both
  sides serves as reflectors and wind-breaks.
• Put paraffin or diesel in the bottom of the tin and place the other part inside, over
  the fuel. First wet the wick in the fuel and make sure that the lower side of the wick
  is in the fuel.

NB: Sometimes, especially when you walk in the dark, it is better not to make local light but rather make use of the light of the moon or stars to find your way. Consequently, your night sight will not be affected and you will be able to see better
