There are stay alive circuits within the TSM module to allow power to hazards for example, with ignition off Ian. Conjecture is that a failure in this module allows a back feed from stay alive source to ignition/start circuit.
Quite how you still get the back feed without TSM plugged in is beyond me without access to full circuit diagram.
Note the headlamps are ultimately controlled by two relays, one the usual dip/main and the other for main beam flash.
