¶1This is an interlocutory appeal by the Commonwealth authorized by a single justice of the Supreme Judicial Court pursuant to Mass.R.Crim.P. 15(a)(2), as appearing in 422 Mass. 1501 (1996), following the allowance of the defendants’ motions to suppress evidence obtained by the Massachusetts Environmental Police. We reverse.
¶2*161The only witness at the hearing on the motion to suppress was Sergeant Charles Ziemba. As found by the judge, and as supplemented by uncontested details, the circumstances were as follows. On July 2, 2006, at about 11:30 p.m., on entering the Swift River boat ramp and parking area, Sergeant Ziemba saw a single vehicle, a green pickup truck, without lights, parked in a cul de sac. He pulled up within fifteen feet of the truck and saw that there was a male in the driver’s seat and a female in the front passenger seat. He observed miscellaneous items on the ground in the general proximity of the truck, specifically a beer can, some sunglasses, and some papers. Ziemba activated his white “take down lights,”
¶3Ziemba testified that the cruiser did not block the truck in any way and that the driver could pull around the cmiser very easily.
¶4In his memorandum and order, the judge distinguished Commonwealth v. Leonard, 422 Mass. 504, cert. denied, 519 U.S. 877 (1996), and noted that the case was closer to Commonwealth v. Smigliano, 427 Mass. 490 (1998), as there were here no facts to indicate that the defendants needed assistance. He found that “the totality of the circumstances clearly suggest the defendant[s were] not free to ignore the . . . inquiry,” and ruled that
“a seizure occurred when Ziemba pulled up closely to the *162defendants] and activated his cruiser’s take down lights onto the defendants] .... The fact that the lights in Smiglianowere blue and here they were white is a classic case of a distinction without a difference.”
¶5Since the Commonwealth had produced no facts that rose to the level of reasonable suspicion prior to the activation of the lights, the judge allowed the motions to suppress.
¶6A review of the cases in Massachusetts and elsewhere indicates that there is, however, a difference between lights used for illumination and blue lights, flashers, or sirens.
¶7In this case, Ziemba did not block the defendant’s truck, use blue lights, flashers, or sirens, display a weapon, or use threatening words or tone or other commanding authority such that “a reasonable person would have believed that he was not free to leave.”
¶8Cases elsewhere indicate that the use of artificial light, without more, does not effect a seizure. For a collection of cases, involving mostly spotlights, permitting such use and finding no seizure, see Campbell v. State, 841 N.E.2d 624, 628 (Ind. Ct. App. 2006). See generally 1 LaFave, Search and Seizure § 2.2(b), at 461 (4th ed. 2004).
¶9The order allowing the motion to suppress is reversed and the matter is remanded to the District Court for further proceedings.
¶10So ordered.
¶11In a case certifying a question (not relevant to this appeal) from the United States Court of Appeals for the First Circuit, Horta v. Sullivan, 4 F.3d 2, 6 n.4 (1st Cir. 1993), the Supreme Judicial Court, in quoting from the First Circuit decision, included a description of “take down lights” as “small white lights affixed to the roof of the police cruiser and located in between two sets of flashing blue lights.” Horta v. Sullivan, 418 Mass. 615, 618 n.6 (1994).
¶12The defendants’ affidavits stated that the cruiser blocked their truck. The affidavits, however, were not introduced into evidence and the motion judge, in discussion with counsel, indicated that they had no evidentiary value. Counsel for Briand indicated that he understood.
¶13In Commonwealth v. Evans, 436 Mass. 369, 372-373 (2002), the Supreme Judicial Court held that the use of blue lights did not effect a seizure where the police were engaged in a community caretaking function.
¶14There was no seizure before Ziemba ordered the defendants to place their hands on the dashboard. At that time, because of the smell of marijuana, he had probable cause to arrest them.
¶15In Commonwealth v. Cavanaugh, 366 Mass. at 281, the court quoted from Dorsey v. United States, 372 F.2d 928, 931 (D.C. Cir. 1967), “If policemen are to serve any purpose of detecting and preventing crime by being out on the streets at all, they must be able to take a closer look at challenging situations as they encounter them.”
