Hi all, as the title suggests my main beam tell tale is not working, according to the MOT history it hasn't worked since 2012.

Main and low beam work fine. The bulb is fine and the flex PCB is not the issue. I have the same problem with two instrument clusters. I have recently changed the cluster as most things weren't working. I am guessing that I have a break in a wire between switch and cluster? All other lights and gauges are working on the cluster.

Any pointers would be greatly appreciated. I am conscious that my headset won't handle too many more separations before cracking / snapping etc. And would like to go in armed with the knowledge rather than have a random poke about.

Thanks.
