It means that one of the position "parking" lights is burned out. It is usually one of the four bulbs in the rear tail light assembly. NOTE: before replacing the bulb, give the bulb housing a light rap with your knuckle. Sometimes the bulb just becomes loose in its mount.
On my 2004 XC90 the lens covering the position light swings open left to right. The bulb is easily accessible.
Volvo uses the term position light for what we here in America commonly call a parking light. If you turn your lights on and walk around your car you will notice you have a bulb burnt out.
This usually means there is a bulb out, there is a bulb failing or there is a bulb that is not seated properly. Check the bulbs in the tail lights especially (there are a lot of them and you may not notice if one is out).

Not sure what you mean about "front position light" however most of the time your owner's manual will address these repairs. See sources and related links below for 2004 Volvo XC90 bulb information.
You can replace the dome light bulb in a 2002 Chevy Cavalier by first prying the dome light cover off of the light. Then, remove the bulb and replace it by twisting the bulb from the socket.
Here is an answer I found. Hope it helps. My Volvo mechanic said it was $5.66 for the bulb(s) and .2 hours for labor. http://answers.yahoo.com/question/index?qid=20090418151932AApJkCv

Not 100% sure if you mean bulb or flasher. Here is the procedure for the 2002 Volvo S80 turn signal light bulb replacement: Purchase the correct replacement turn signal light bulb(s) first, before disassembling the vehicle. See sources and related links below for replacement bulb information. Then consult your owner's manual for the turn signal light bulb replacement procedure. As simple as it sounds, the owner's manual is the best place to start for bulb replacement instructions and illustrations. You may want to consider replacing both left and right at the same time in order to keep brightness and color equal (optional).
