The rear brake light fitting is holding rain water and literally pours out after a downpour, when set off driving, so much that it can cause multiple tracks down the screen that have to be cleared with the wiper. The dealership from where it was purchased have tested it with a jet wash and cannot see the problem. I cannot explain it clearly enough to them and they don't believe there is a problem. We have taken photos of water and condensation inside the fitting.
Hi, thanks for your reply. We have taken video with my son in the back filming as we drive along to show how much water comes down the rear windscreen. It has just stopped heavy raining and this video clearly shows the affects. We have also taken photos of the light fitting, this time with the brake light on, which shows the water up more clearly inside the light fitting. The dealership have offered to run more tests, but I can't see what spraying a jet wash onto the car will do - they don't seem to want to take it for a test drive or look into it further. Thanks for mentioning about the rear washer, I will certainly mention it to them.
