The ABS is the base system, and it generates a speed signal that is used in the engine management. The ESP and probably BAS lamp is on because these 2 systems run in the ABS.
Abs problem are either a front sensor or rear sensor/reluctance ring rusted, the car should go on STAR as you can spend a lot of time and money searching for a fault, STAR will tell you the corner with the fault.
With no speed sensor the engine does not know what to do in relation with the gear box, and the system locks up for safety.
The brake lamp switch could be the problem, but not sure, but its well know to kill the speed signal within the ESP ECU. They only cost a few £$ and easy to fit.
If the speedo still works, then still some speed signal.
