Can anyone help me find a Perry Mason episode?

I teach motor vehicle crash investigation courses. I recall an episode of Perry Mason that involved a person being run over によって a car and it was written off as an accident until Perry got the driver on the stand. The key point was the driver saying how he saw the person just before impact "in the glare of the headlights," but Perry produced the car's headlights that showed they were actually off at the time, thus 表示中 that the man was both a liar and murderer. I want to use this as an example in class. The details are fuzzy but essentially accurate. Any help is appreciated.
