If it happens, like with me, that Honda can't find you the one that perfectly fits your housing with the attachment bosses in the right place, search the archives here for stuff about to retrofit a cheap, commonly available new bulb into the original sealed-beam lamp.
I used a halogen, like this one..
Basically it involves carefully removing the front glass lens, removing the inner bulb and gluing a new bulb in with silicone.. replace the front lens.

..only have one "beam" but it's better than nothing.. cars see me coming and i'm satisfied.
