Several members of the famous Bill Stroppe Lincoln Team wore the Bell 500 in the Carrera Pan-American Road Race in 1954. A Bell helmet was used in the Indianapolis 500 for the first time by Cal Niday in 1955. Niday crashed during lap 177 of the race and suffered several major injuries. Despite suffering a skull fracture, Nidal credited the helmet for preventing even more serious injury. By 1956, helmet sales were far above projections. This resulted in the formation of the Bell Helmet Company as a subsidiary of Bell Auto Parts. The helmet operation employed at least four people working full-time producing helmets in a facility next door to the original Bell Auto Parts location.
