These are sealed-beam. The problem is that they're so high off the ground that they are about eye level with most drivers, meaning they'll shine in their eyes more than other lights.

There are plenty of good sealed beam LEDs from reputable, American companies such as JW Speaker, Peterson, and Truck-Lite. Sample catalog below:

I hope you chose something from one of the aforementioned companies. The aftermarket clones are just that...poor-quality clones.

Anyway, being able to see wet pavement and puddles is almost irrelevant. Wet road surfaces are good specular surfaces, which means that light from your headlights is bounced away from the car. Dry road surfaces, on the other hand, scatter light in every direction, and as a result, dry roads appear to be better lit than wet roads. However, simple physics dictates that the amount of light hitting a road surface doesn't change just because someone poured a few gallons of water onto the road. The amount of light hitting the road surface is a property intrinsic to the headlamp.

And really, there's way too much emphasis placed on how bright a wet road appears to a driver. Last time I checked, most obstacles (deer, pedestrians, disabled vehicles) were above the road even when the road is wet. The amount of light that is reflected off something above a wet road wouldn't change much whether the road is soaking wet or bone dry. And it's the light that is reflected off an obstacle that's important in perceiving those obstacles (well, that, and the contrast of the obstacle).
