Abstract
Abstract An auxiliary multi-purpose signaling indicator for a vehicle is constructed of three elongate sections which include a central section which lights when the brake of the car is depressed and left and right sections which flash for indicating left and right turns. Normally the three sections are arranged along a straight line and operate in a mode which is conventional for brake and turn indicators. In case of an emergency, the left and right turn sections of the signaling device may be bent toward each other to configure the device into a triangular shape. Each side of the triangle contains one of the indicators. The distal ends of the left and right sections are linked mechanically and electrically such that activation of the emergency flasher of the vehicle provides a triangularly shaped flashing light beam.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
166 words
An auxiliary signaling device for vehicles, comprising: a braking indicator for indicating that a vehicle is braking; a left turn indicator; a right turn indicator; and a first flexible connection for flexibly connecting the left turn indicator to a first location on the braking indicator and a second flexible connection for flexibly connecting the right turn indicator to a second location on the braking indicator, the braking indicator and the left and right turn indicators having a normal position for signaling braking and turning of a vehicle in which normal position all indicators are in first fixed positions relative to each other substantially along a straight line and having an emergency indicating position the signaling device is configured into a generally triangular shape, the first and second flexible connections being bendable to enable the left and right turn indicators to be moved to cause the signaling device including the braking indicator, the left turn indicator and the right turn indicator to together assume the triangular shape.
Claim 2
Dependent Claim
166 words
