PA-18 Pilot reported a loss of directional control during landing. A taxi light was damaged; the aircraft sustained a dent in the cowl; a prop strike; and no injuries.

Narrative

I was intending a touch and go on Runway XX at ZZZ and then to leave the pattern. Had normal downwind; base and final approach. Touch down was normal and at normal speed; between 55-60 mph. After touchdown; during roll out aircraft began to aim and turn to the left. I corrected with right rudder; and added a some power to give the rudder more authority. The combination of right rudder and power was too much and the aircraft began to rapidly turn right. As the aircraft continued to turn right I lost control and the aircraft began to swing around into a ground loop. It did not finish the ground loop but veered into the snow alongside the Runway XX where the taxiway enters from the north. A taxi-light was damaged and the aircraft sustained a dent in the cowl and a prop strike; as the prop was stopped by the snow. There were no injuries. The event was inadvertent and unintentional. It was due to pilot error; the over correction of the left turn. There were no near misses or traffic conflicts; though the runway had to be closed for approximately 60-90 minutes till the aircraft was removed.
