Technically true...but one of the SADCASE guys has an old Moggy Minor cop car and never has any issues. A cop even told him as long as they not on until he gets to shows he's unlikely to have any problems with the law.
Decades ago a friend of mine was a Hella distributor and he purchased a dark blue Austin / Morris 1100 and he installed a blue light on his car , as a demo light !

I know that some years ago classic car owners were asked by police to either remove or cover the blue light when driving the car to and from shows (technically speaking, they are right - having a blue light on a non-emergency vehicle being driven on a public road is an offence, whether the light is on or not). But it may differ from one police force to another.
