dont know if anyone else has had this problem, but took my 2010 1125 CR in for 1st service today. 87 mile ride in rain, and all was ok with the bike except the brake light was stuck on. it was not a switch or wiring fault, but water getting into the light and shorting it out. the tech dried the light out and it was ok, but stuck on again when i got home after another wet ride.

i know the light was ok when i left home as i checked it

just a heads up as if you brake and someone behind doesnt know you are braking it could be a danger

The 2010 light is completely sealed. Unless someone cracked open the lens?

I'm lost

My bike sat out in the rain all night before the last ride and my brake light was on during the ride from Hals to the factory and I didn't know it.
I was wondering why everyone behind me was staying way back.
So some of us checked it out in the factory parking lot and it came down to the front brake light switch.
While I was doing the factory tour I told my guide about it and a little later he came walking out with a new switch,we installed it and bingo no more problems.
Thanks to everyone that got me fixed up!

The front brake light switch wires on any bike with the ZTL2 system are pretty much exposed.

Crappy design, there's no connector cover, just metal connectors out in the open.

If water settles between the two, it'll cause the light to come on.

I went and looked on mine. The fittings themselves (spade lugs?) are shrink wrapped but where they slip on and butt up against the switch housing is very slightly exposed. Maybe apply some dielectric grease if that is the problem spot?

"water getting into the light and shorting it out. the tech dried the light out and it was ok"
What a dumb ass tech. A short in the light assembly WILL NOT make it stay on....nor will water complete a 12 volt circuit that requires amps to operate. Milli-amps.......maybe.

water conducts electricity (unless its demineralized)

simple

The 2010 tail light is only a few hundred miliamps, water would have no problem conducting that, and could easily conduct more.

But picturing someone using a blow drier on a light that to my best guess wouldn't leak if you threw it in a pool, is kinda funny :-)

that thing is sealed up good and tight at every angle.

Sounds like a dangerous problem either way.

So if I leave my X1 out in the rain with it's exposed battery terminals.....it will go dead from the short circuit as well as I will be electrocuted if I put my wet thumbs across the terminals. Don't be dumb asses here. It's 12 volts DC we are talking about. Yes it will conduct electricy,but a very minute amount.

If you had a solid stream of water from one battery post to the other it would cause a drain.
Of course it would be a small drain, but enough time and it would kill the batteries charge.

After thinking about it more, your right. It's not enough juice to power even a few hundred miliamps at 12 volts. But if water hits the right circuit it could short it out.
With that I'm not sure what would cause the light to stay on then besides a sticking switch?

Well it looks like there could be an issue with the LED tail lights - I've got exactly the same problem - I suppose that it could be water getting into a brake switch as LEDs don't need as much current to activate compared to bulbs.

Water will easily create a short circuit no matter what Volts or Amps you are talking about.
I work on trains and we often have problems with water getting into junction boxes and creating dead shorts and were talking 415V.
