Intermittent Brake Light Problem
Have a 2004 Carbed FLHT with 13,000 miles.
Coming back from Knoxville, the cruise control would not engage. Buddy riding behind me flagged me over and told me that my brake lights were stying on. Turned bike off and on, brakes light was off. Happened again after another 500 miles. Turning off and on fixed it again. After a couple hundred more miles the brake lights were going off and on. Pulled off and using the front brake had no effect, but using the back brake would result in light turning off then back on again.
Kept getting worse as I went along the last few hundred miles, when I got it home brake didnt appear to be dragging at all spun freely even though the light was on. Only the rear pedal seems to have any effect on it, but does not last long.
Any ideas?
Thanks in advance

A couple things just occurrred to me: Keep in mind that I don't know the wiring diagram for your ride.If the above suggestions don't fix it,can you safely disconnect the cruise unit for testing perposes? Do you have any type of brake modulation devces installed?

No rain, just a few bumpy spots. I do have the Harley module that turns uses the turn signals as additional brake lights.
Thanks for all the suggestions so far.

RE: Intermittent Brake Light Problem
The HD cruise is wired to disengage whenever either brake switch is closed. The switch should close by the mechanical action of squeezing the brake lever or pressing the pedal; the switch should otherwise be open allowing the cruise control to engage.
Since your brake lights were on, the switch was closed and the cruise would not engage or stay engaged. If the problem is the rear brake, check the switch at the pedal to see if there is any debri, etc. preventing the switch from remaining open. Also, check for any wear or abrasions that might cause a short to close the switch.

RE: Intermittent Brake Light Problem
I knew a Sportster rider who had leather fringes on his levers. At highway speeds, the wind drag on the right side fringe was enough to activate his brake light. He was more concerned with style, so he just lived with it.
