I have twice been back to the dealers in the last few months to get this changed, because of the brake light not coming on. I decided to test the old switch once off the bike and discovered it still worked. I realised it's actually the little rubber boot over the switch is not uncompressing due to the cold weather. Is there a spray on lubricant that will stop the rubber becoming affected by these cold winter months?
KTM Duke 125 front brake light switch issues

Never come across a rubber boot return spring,i suspect the internal return spring and plunger are seizing up,not knowing your switch set up have you tried squirting wd40 inside the rubber boot ?
Silicon oil spray or grease will keep the rubber supple.
Have you any pics?
yeah it's not a rubber return spring, I guess it's just supposed to be a waterproof cover. I will give the silicon spray a try.Thanks
My lad has the Duke 125 and he has had the same problem with the brake switch, KTM changed it 2 weeks ago and its started its problems again already.
need one brake to work a brake light, as long as the rear brake works the brake light that's fine, just remove the front switch & the lead that runs to it, if it's not fitted it doesn't have to work.
There's never been one on my bike from new " />
I don't get angry, I get even
I sorted this issue, it seems the switch is fine, its the cold weather affects the cover, give it a squeeze then pull the lever, it will probably work. I covered it with silicon grease and so far it's been ok

I had the same problem, KTM have a fix! Simply remove the wire around the rubber boot, remove the boot and throw it in the bin - works perfectly well. The problem is that the rubber stiffens in cold weather.
