[led revcounter]

Hi im am not trying to repair a gauge i am trying to make a new one. My bike currently has a normall electronic gauge fitted but it is located on my tank. Were as my speedo is infront of my handle bars so i would like to make a bank of say 12leds mounted round my speedo to work as a revcounter. I have seen some done like this on youtube and they look good. My bike is a 1992 yamaha vmax which i have customised with varius one of parts made by my self with the help of the bystronic laser machine i operate at work but dont tell the boss ::).
So any helpwould be good.
cheers dave
