hey all,purple hobbit had a light go on the instrument cluster so thought while changing it i'd change them all to blue,now they don't work,i've tried putting the old ones back in and still nothing,the usual lights work,indicators and check light etc when turning the ignition on,but at night when turning on the lights it's just blackness,makeing it near impossible to tell how fast i'm going,or how much petrol there is,i've checked fuses and all seem fine,so now at a loss and ready to break something,so please has anyone got any ideas? much appreciated
