MAZDA 



Not the name o/*a thing, but the mark, of a service " 



What is it? 



Motorcycle or car? If it is a car, which lamp is out — left or right? 

 Lamp-unreliability is both dangerous and unnecessary. The 

 known high standards of Mazda Service are sufficient to make 

 the cautious and considerate insist on having Mazda Lamps — 

 Lamps marked MAZDA. 



MAZDA is the trademark of a 

 world-wide service to certain 

 lamp manufacturers. Its purpose 

 is to collect and select scientific 

 and practical information 

 concerning progress and 

 developments in the art of 

 incandescent lamp manu- 

 facturing and to distribute 

 this information to the 

 companies entitled to re- 

 ceive this service. 



MAZDA Service is centered in 

 the Research Laboratories ofthe 

 General Electric Company at 

 Schenectady, N. Y. The mark 

 MAZDA can appear only 

 on lamps which meet the 

 standards of MAZDA 

 Service. It is thus an 

 assurance of quality. This 

 trademark is the property 

 of the General Electric 

 Company.
