Suddenly, my brake lights have stopped working. 2 weeks at my very competent local garage & still no luck... Could anybody please advise on all the things to check? The switch looks like it disconnects rather than connects the circuit when you press the pedal, which is new to me & is connected to the turn signals somehow? Totally lost even with wiring diagrams! Any advice would be really appreciated as it’s a crazy thing for her to be off the road for!
