Yeah, any reputable parts store can sell you a non sealed beam light. Just need the measurements of the old ones to make sure they don't stuff it up. Then you'll be able to run h4 globe you choose.
If you're really keen you could wire up separate relays to make sure there's no voltage drop in the old wiring.
