Later on, even after changing the helmet color to black, they left the logo on the right side only, due to the teams new found success & uniqueness of the logo. The Steelers are now the only team with a logo on only one side of the helmet.
The Pittsburgh Steelers has only 1 logo on a side and not on the other side

There is also the face mask that protects the face, a chin strap that holds the helmet on, and a mouth guard to reduce concussions and protect your teeth.
