No, the beam pattern is in the lens of the light. You need to swap the entire light assembly and bulbs if you didn't already have halogen bulbs to re-use.
I think Matt has sealed-beam headlights, which means his bulbs are his headlight assembly.
I'm not sure if you can by E-code sealed-beam headlights in that size though. But Hella does makes an E-code sealed-beam conversion which takes the H4 bulb.
Note: The Hella headlight assembly comes with new H4 bulbs. The catalog doesn't say that, so I ordered new bulbs at the same time (this being for a fleet of F650s). I could have saved almost $200 in extra bulbs had I know that.
I actually got a better price ordering them through CarQuest, but I had a fleet account so I'm not sure if that would be the case for retail sales. At the very least I'd think they would match the Summit price, since doubt they were losing money when they sold them to me.
