As far as I can see, there is no means of focusing this arrangement. What was the previous owner thinking?? Is this the remains of a sealed beam conversion?? I am debating trying to fix this or simply replacing the entire unit.
I think you have a pretty common problem. That looks stock to me, the lights were not "sealed beams" as in one headlight lamp. You just remove the bulb and pull the reflector forward and see what you have behind it. You seem to catch on pretty fast to stuff, it's self evident. May just have to squeeze the socket or the spring slipped out...you'll see it. You "focus" the lights by loosing the mounting bolts and move up and down. The link below is just one product and locally most auto stores sell socket stuff. I don't believe you have to be careful handling the bulbs with tissue as they are not halogen...
