Narrative:

I was flying with the owner of a tailwheel aircraft who had just purchased the airplane. I was in the right seat as instructor and he was in the left seat as PIC. It was agreed to prior to the flight that he would be the PIC as required by his insurance company. In addition; the airplane only had brakes on the left side; and it was discussed prior to takeoff that the owner would be responsible for application of brakes during the flight. An approach to landing was being made with a 30 degree crosswind; wind speed about 8 KTS. The owner was attempting a wheel landing. He had a slight bounce and the airplane turned to the left; not aligned with the runway.I attempted to recover by applying aileron into the wind and opposite rudder to align with the runway. The airplane was in contact with the ground and I felt that applying full power for a go-around at that point would make the swerve worse and that brakes applied correctly would correct the swerve. I told the owner to apply right brake; the aircraft continued to turn to the left and the plane had turned from [one] runway onto [another] runway at the intersection; [and] I repeated [my instruction] to apply the brake. The plane was on the outer south edge of the runway and just prior to the aircraft stopping the prop struck a runway light. Proper application of brakes could have prevented the event.
