Petzl Tikka Head Torch: This great little headtorch uses 3 LED's and AAA batteries (included) to provide light on the go and handsfree.
 
The Tikka is small enough to fit in your pocket and the LED's have amazing power compared with a normal bulb. 

The triple LED bulbs provide 27m of lighting and won't have any blank spots.  The bulbs are set out in a streamline formation for maximum illumination and the headlamp can be tilted for multiple angles. 

An elastic headband holds the lightweight Tikka to your head and it is water resistant for use in the rain. 

The Tikka is a real classic, at a bargain price!
