The TR 4's I have seen never had a flash to pass.  The headlights are turned
on from a knob on the dash.  The only switch to go from high to low is the
foot switch by the clutch.  My means of "flashing" is to step on the switch
twice.  The only column mounted switches on the 4 was the blinker and
overdrive (if installed).
