To be honest halfords dont have the best rep.. but if all was put back in place then its a case of the rubber perishing on the light covers.. the only person to blame is the tree which was the source of the rubber... or maybe BMW for using such a design
I would removce the rear light covers.... after you have dried out the light try using some gummi on the rubber, or a silicone spray to get some moisture back on it.... then reseal.. give it a couple of days.. if its still has the condensation then its a case of getting a new one seal from BMW
