Application'filed January 20,1928} Serial no. 248,200 i The present invention is directed to in1-' provements in traffic signals, and has for its primary object to provide a device of this character capable of being installed upon a vehicle and conveniently operated for indi iating to following traffic the intended courseof the Vehicle equipped with the device.

Another object of the invention is to provide a device of the character specified, so constructed that the signal will be illuminated when the armthereof is extended and "ex-.

tinguished when the armis contracted.

Another object of the invention is to pro vide a device of this character soconstructed .15 and arranged that the driver of a vehicle equipped with the device can indicate to approaching and following traffic, as well as to pedestrians, the intended course of the vehicle, without the necessity of extending the arm therefrom, which is now customary, and while no doubt, effective, nevertheless adds to the discomfort of the occupants of the vehicle in cold weather, since to do sonecessitates opening the window next the driver;

a While the drawings illustrate a preferred embodiment of the invention, it is to be understood that in adapting the means to meet M specific needs and requirements, the design may be varied and such other changes in the minor details of construction may be resorted to within the scope of the invention asclaimed, without departing from the spirit thereof.

and the merits thereof, reference is to be had to the following description and the drawings hereto attached, in which,-

.1 Figure l is a fragmentary front view of a of'FigureB.

Another object of the invention is topro-- vide a device of this character which is neat in appearance, effectlve in operation, and i in which is engaged the vehicle showing the device attached thereto and inits extended ,orjoperative position;
