Hi, had similar problem. Turned out to be the brake switch...

If it's a Mellor bus check all lights are working, if there's any issue there are two panels on either side at rear , if you remove these panels you may find a set of bulbs on the heatsink and the bulbs maybe blown. They did this for cheapness and it's a really nasty 'bulb to led' modification/s, IF, you can call it that!
