THE GAUGUES DO NOT HAVE A BACK LIGHT, THEY ARE ONLY LIT UP BY THE LEDS ON TOP OF THE CLUSTER, IF YOUR CAR DID NOT HAVE THE WATCH DIAL GUAGES THE LED LIGHTS WILL NOT WORK ON TOP, ADDTIONAL WIRING WILL NEED TO BE DONE. This instrument cluster came off a 2005 Volvo S60R 6 speed manual with 115,000 miles, part# 30682280. This instrument cluster is in really nice shape for the age, lens is really nice with a few minor scratches. Please match your part numbers before purchasing.
