PA vehicle code section 3112a3i is the red light section, in short it must be a steady RED indicator for it to be a violation.

The Supreme Court ruled long ago that we can run any tag we can see on any roadway and public areas (like malls, gas stations, etc) and that there is no expectation of privacy and that running a plate and checking the registered owner is not violation of anyone's 4th amendment rights.
