Having trouble with my left led tail light with moisture getting in, got it working again previously but it's packed up again. Just wondering if I order a new one will I have to get new wiring to the light as that wires are also very damp. Has anyone else has this problem

If you can dry the connectors and run off any corrosion then you should be ok.
