When I stopped buying by part number and instead by wattage and base style, I finally got a set of bulbs that have all been going strong for over six months.

So forgive me if this has been covered before, but I wanted to share what I’ve learned because I had no luck searching on the problem when I was trying to fix these.
It was time to get my wagon inspected to renew the registration, and around here they won’t pass you unless ALL your lights are working. Judging by the number of XC70s I see around town with dead position lights and brake lights, I don’t think I’m the only one dealing with this.
I kept replacing the bulbs, which we all know is the biggest pain in the ass considering you have to remove every interior trim piece to get to them, and they’d work, but by the time I got to the inspection station one or more would be burned out. Over many trips to O’Reilly and a lot of time with the manual, I finally discovered the problem isn’t the car, it’s the manual itself.
Either Volvo severely screwed the pooch on parts numbers in the manual or lamp producers have changed the specs since 2001, but the wattage on almost every bulb has gone up since produced. When I stopped buying by part number and instead by wattage and base style, I finally got a set of bulbs that have all been going strong for over six months. If anyone finds this helpful I’ll dig up the part numbers for the bulbs that actually work, stay working, and don’t get so hot that they melt the blades. The only one that’s really difficult to find is the variable wattage fog light/position light on the driver’s side – I finally compromised with a lower wattage bulb because I couldn’t find one with the correct watts that also had the offset base.
