Thanks brett,

i acutually already ordered some leds from a company in aus,
i reinstalled the cluster while waiting for my leds to arrive to find some some lights didnt work, after messing around a bit i found the solder on the circuit board where the bulb housing makes a connection is very thin and has worn just enough to make a faulty connection, so it needs some playing with to work, but a bumpy road will break connection again.

so i think resoldering the circuit is the only solution
