 company ordered the Bosch engine and was soon breaking automotive speed records. Honold continued work on faster and more powerful engines.

In 1913, Honold helped develop the automotive headlights that are used today. Although lights had been used to some extent for night driving, the early lanterns did little more than to draw attention to a vehicle, and were of little use for illumination. It was Honold who conceived the idea of placing curved mirrors behind the lamp to increase the amount of light without taxing the automotive electrical system. Honold also helped develop the Bosch car horn. Honold died in Stuttgart on March 17, 1923, at the age of 47.
