Maybe you're not sealing the USB charging port properly. If you open the charging port and shove a bit of paper towel in there, does it come out damp ?
If you don't have mudguards, you may be splattering it with too much road slime. Clingfilm is my goto technology for this sort of problem.
Could it be a bit of road gunk that's been transfered to your USB charging lead, and is contaminating each new light ?
