Was going to go for a run today and when I tested the indicators before setting off I realised I had no left hand side at all. Right is working fine but not the left. While checking the bulbs I found a lot of water inside the lens, and the fittings are coroded! Can I assume that its the fittings etc and just go all out and replace them with new LED's maybe or is there a chance its the Switch? Am I right in thinking if the circuit isnt complete for both front and back the flashing unit wont work?
