Does the use of the emergency lights on a police car constitute a showing of police authority?

As pointed out in Mendenhall, supra, 446 U.S. 544, the presence of multiple officers is a factor that can contribute to a finding a suspect has been detained. (In re J.G. (2014) 228 Cal.App.4th 402, 412-413.) The use of the emergency lights on a patrol car can be a circumstance that would indicate a person must yield to a showing of police authority. (People v. Bailey (1985) 176 Cal.App.3d 402, 405-406.)

We next consider whether the circumstances of the "contact" in this case objectively became a seizure.
