What does Bulb Failure Position Light message mean and what is the fix? All
my lights work properly.
 
Check your parking light bulbs to see if all are working if one is out
change all of them

What model car is this? The sensor is notoriously sensitive and can be
triggered if the bulbs on each side are mismatched.

This has to be one of the newer ones (S80, new V70, S60 etc.) that have
the text warning. And Volvo bulb failure sensors haven't compared
current from left to right since the end of the 940. (760s from 1988
and 850s also use the new type sensor.) This type of sensor senses the
current to each bulb and turns on the warning if the current falls below
a certain amount. So the bulb can still be working and turn on the
light. This type is not sensitive to left to right balance so at least
that's an improvement. It is still sensitive to dirty sockets etc.

Ah, good to know, my only experience is with the 940 and earlier cars.
