There is a factory bar / bracket for the P2 and P3 wagons that bolts around the license plate mount. I don't know if there was one for the P80s.


Lower is better for fogs, but then they get bashed by rocks sprayed off truck tires.

850 1994 year model had bracket 9134 679-1

Look to Nordic Climates and their Volvo boards.
That three fixture setup is a quite popular in
Scandinavian countries.

Not on an 850 but great videos with details on mounting and wiring.
