I recently became a proud owner of an '05 450 with the brake light permanently on. With some testing I deduced it was the rear pressure switch causing this. I have replaced it twice now only for the switch to fail on both new switches after only a couple of rides. Redline have kindly replaced it under warranty once but what are the chances of them doing it again? I have been reliably informed that they are prone to failure but this repetition so quickly points to another problem? Has anybody come across this problem?
