2001 Harley Davidson FLHTCUI Electra Glide Ultra Classic Back brake failure Rear break light switch failure

Hi Anonymous, this problem is usually cause by the front brake light switch being out of alignment or the button not retracting all the way keeping your brake light on in a closed circuit, depending on your model year. 1996 and earlier models the right handlebar switch housing had to be tight up against the front brake control housing in order for the front brake light switch button to be fully compressed to stop continuity. In 1997 and later models the button was alot shorter and was more of an alignment issue in the switch housing. Rear brake light switches located in the rear brake line TEE can also fail in the closed circuit condition but extremely rare, usually they fail in an open circuit condition where the brake light is not able to activate.
