i've had this on my b13 since i've owned it, it would go off if i pushed down on the brake lever hard enough..
so took the console off today and adjusted the ebrake cable and checked out the little button that activates the light on the dash, it worked just fine turnin the light on an off but for some reason the thing on the lever that pushes the button down couldnt push it down far enough to make the light go off any more.. so i jus bent the tab down a little so now it pushes the button down far enough to turn the light off..
was hella easy an i shoulda just done it along time ago..
