Volvo Repair: XC90 - Bulb Failure Position Light, bulb failure, warning light

Question
On my 2004 XC90 I'm getting the message "Bulb Failure Position Light".  One mechanic said the Position Lights were over the rear license plate where one bulb was out, but now replaced.  The warning light is still on.  Are there other position lights?  Thanks Roger, you're the greatest!

Answer
Gregg, those bulbs are such a pain.  Most likely its one of the marker bulbs in the taillight assembly.  The bad thing is having to take the whole unit out to access the bulbs.  We dont charge to do this.  Maybe your mechanic can help you out and not charge you either.  Roger
