摘要: A light bar (100) for mounting on an emergency vehicle to provide warning signals. An elongate body portion (102) has axis (104), the adapted be mounted so that (104) traverses (106) coaxial with direction of travel vehicle. At least three vertically spaced lighting layers (118, 122, 130) are provided, each layer having at one emrgency source, sources cooperating a transient high intensity signal 360 degrees around (100). four linear rows (142, 144, 146, 148) as viewed from top also being substantially parallel row two sources, located in and rows.
