The things that are in the corner of your rooms,that show a red light when you move around,i am after the same thing,but i want the light to be blue,any ideas where i can get them...thanks

We've got blue ones and they were fitted by Blackminster Alarms from Evesham. They may be able to tell you where to source them.

They are both LEDs (Light Emitting Diodes). The easiest place to source them would be Maplin Electronics (in many UK cities and towns). You would need to be able to solder to fit them.
