anyone swap the fog lights with different bulbs?

When I asked volvo what bulb type the fogs and driving lamps were they only had a volvo part number. I called Sylvania to hopefully get a h1 or 9005 type cross match but they said it's a volvo specific bulb.

Does anyone know what bulb type could fit in there from experience? I seen a guy have hid in em before so it's been done. I am looking to put some led bulbs in mine because I work offroad and the filiments don't last with the vibration.

 

Sorry I didn't mean volvo made it. I think Sylvania does but it they said it doesn't cross with any other bulb. That would obviously be because the plugs different but that's easy to change. I just need one to fit in the socket.

 

Hid bulbs are the same socket wise. If a h1 hid bulb fits then a h1 halogen or led will too.
