A modification is now in effect in order to prevent premature failure of the stop light switches, Part #134529, due to the switch being physically damaged by the brake pedal lever.
The modification consists of removing the switch assembly from its mountain bracket. Discard the fixing nut, Part #JN 2111, and plain washer, Part #WM 0711. Refit the switch to its mounting bracket but first place a new plain washer over the threaded portion of the switch between the mounting bracket and the new nut, this hs the effect of increasing the clearance between the switch plunger and the brake pedal. The thicker nut will also act as a pedal stop. Retroactive action is not considered necessary.
