What bulb ?

[alanscottgraham]

Just trying to order a set of nightbreakers for my '97(P) 855R and have seen two different 'bulbfinder' sites, one says H1 the other H4. It's just the normal headlight thats gone not the main beam. Can anyone help?

The 850s used H4's up til 1994, then Volvo changed to the twin compartment headlights and they used H1 bulbs for both dipped and full beam. So yours should be H1
