Helmet
A helmet has a helmet shell and a visor pivotally connected to the helmet shell. First and second helmet electrical contacts are attached at both sides of the helmet and are adapted for electrically connecting to an electrical power source. First and second visor electrical contacts are attached to each side of the visor. The first and second visor electrical contacts are in contact with the first and second helmet electrical contacts respectively, at at least one position of the pivoting visor. First and second electrical wires are electrically connected to the first and second visor electrical contacts respectively.
