Volvo Repair: 2004 XC90 fault messages, service reminder, bulb failure

Question
I have a 2004 XC90 with a fault message and yellow indicator lamp illuminated. The fault message reads (Bulb Failure Position Light) Do you know what causes this indication and the repair? I am also trying to reset the service reminder. Any assistance would be greatly appreciated.

Answer
Thats a bulb in the back and unfortunately on those things, you have to take out the assembly to get to the bulbs.  Not too bad to do.  To reset the service light, Turn the key to pos 1 hold the odo reset button.  While holding the button, turn the key to pos 2.  Wait until the yellow triangle flashes and release the button.  Light is now set.  Roger
