    摘要: This invention relates to a signal warning light device designed to be mounted on the roof of an emergency vehicle. Normally this device, in use, would appear to be a frame holding a line of lights across the top of the vehicle. However, at the scene of an emergency, under control of the driver, bars pivoted at the two ends of the frame would be automatically swiveled upward. When raised fully, the bars would appear vertical and with its vertical array of lights woudl provide approaching drivers with an advanced warning. By limiting the movement of one bar to an acute angle and not fully raising the other bar the effect of a pointing arrow or spear head would be obtained. Thus by selectively controlling the bars to be raised, traffic could be directed to proceed left or right or if the both bars were raised partially, signals to stop, slow as well as right and left may be given. Sequential flashing of the bar mounted lights would emphasize the message when directed toward the "point". Reflex material can also be used instead of electric lights.
