The use of two red lights on the left turn signal allows for redundancy in case one of the red lights burns out, while saving money by requiring only one signal for left turns per direction that needs one.

How do traffic lights change?

The primary, reliable and most common traffic light sensors are induction loops. Inductive loops are coils of wire that have been embedded on the surface of the road to detect changes in inductance and convey them to the sensor circuitry in order to produce signals.

What happens if you run a yellow light and it turns red?

If the yellow light turns red during the fractions of a second it takes to cross between the stop line and the intersection boundary, a citation can be issued. At a red-light camera intersection, this ticket is automatic. Another consideration is where do you actually have to stop.
