Since converting to 12v I haven’t had much use for the map reading light I bought from Sodbury a couple of years back.  Decided to use some cheap LED strips - the sort boy racers use as underlighters - and a length of platic round bar to convert the lamp to 12 volts and the 21st century.

The Lamp
Milled a slot in the pastic round bar and glued the LED strips in place
High-tech electrics.  Have looked at fitting a battery but can't find a lead acid one of the right size
Finished product.  Slightly brighter than the original flourencent bulb and uses much less power.
Sould come in handy when we go to Wales in a few weeks.  Still need to think about sleeping and heating issues though...
