If an emergency vehicle comes across a RED light, it has right of way and does not need to wait.
Crowded road due to limited lane space is an impossible situation for an Ambulance to move even with such device installed - unless the idea is to turn the light green and let ALL the vehicles ahead through..until the emergency vehicle crosses.

Yes, that is the purpose. Vehicle ahead move thru the crossing and pull on the side to let the emergency vehicle pass. As said, I have observed it in my city.

On a Red light they have to proceed with caution, whereas on a Green light they can proceed withour caution. The idea is to reduce the time to cross the intersection by changing the light to green

Traffic signal preemption is a type of system that allows the normal operation of traffic lights to be preempted.
in the case of emergency vehicles they are frequently integrated with the vehicle's emergency warning lights. When activated, the traffic premption device will cause properly-equipped traffic lights in the path of the vehicle to cycle immediately, to grant right-of-way in the desired direction
This is implemented in emergency vehicles for kitchener / waterloo region
I know at intersections without traffic lights, public transport buses while taking left turn specially activate under ground sensors, so that, the traffic in other direction stops due to red lights. These under ground sensors activate automatically for any body having particular weight load. Even if you drive a private bus of same weight, the traffic lights will be activated.
Read in the Toronto Star today :
A Mississauga firefighter has been charged more than a month after a fatal crash involving a fire truck.
Kimberley Schulz, 42, died on March 6 when the fire truck, which was responding to a call, collided with her car at the intersection of Britannia Rd. W. and Belgrave Rd. in Mississauga.
Police were investigating whether the sensor system that is meant to change traffic lights had not switched the light.
When an emergency vehicle approaches a traffic light, the vehicle supposed to have a green light, while all three other directions are supposed to have a red light.
It is now clear that the fire truck had a red light, police said.
Jarrett Johns, 35, of Toronto, has been charged with failing to stop at a red light.

Apparently emergency vehicles HAVE a sensor to change the lights and are liable to stop if the lights are RED . The firefighter is charged with failing to stop at RED .
