As well as user defined processes such as 'Alley Lamps' and 'Run Lock' (Run Lock allows the engines to continue to run without the need for keys in the ignition) to avoid the vehicle being stolen whilst attending an incident.
The lamps are then fitted, typically for a Police vehicle they will have an external roof lightbar, blue repeaters and flashing headlamp relays. The siren can also be controlled by the original vehicles horn switch (steering wheel). This is only activated when the '999' or 'Siren' button is depressed on the controller inside the vehicle.
