elv the 560 sl is a 107 body and not a 129.so david could it be bossible that the light bulbs are burned out ,or did they sudenly at once all fail?the signal and tail light bulds try and replace.Now for the instrument cluster.do the other light in the dash work,like radio heater push buttom unit?if they dont work either than the reostat in the combi cluster is defective,otherwise try replacing the instroment cluster bulds...well i hoped u checked the fuses.Good luck Harald
