Water droplets in the lens isn't a loose bolt problem!
That would be a loose screwiin bulb connector....as in, they didn't install the new high beams correctly, or retighten them properly!
The loose wheel well shrouds
could contribute to water from the wheel spinning into the area more heavily. I would go to Autozone, Pep Boys, O'Reilly's and get some of the generic plastic pop-in connectors; drill some holes where needed, and pop them in to tighten the shroud up a little. That problem could be due to either the tech didn't snap the edges of the covers/shrouds back in corrcetly...or, man-handed them so badly that they broke some of the retaining edges, or lost the pop-in connectors that were there. (I know, because I've done this mysely when in a hurry!)
