Light, like any and all waves is pure energy. It doesn't contain any particle which could give it mass.
According to Einstein it is possible to convert mass to energy and there is a likely possibility of doing the reverse operation as well but the energy never has a mass for the external observer of the energy.
Maybe if you went at light speed following the same trajectory that then and only then would you observe a mass instead.

The photons in light do have a mass, but it is negligable in most problems as it is so tiny.
Energy is made up of electrons which have a mass of 9.11 x 10^-31 kg.

negative...no mass for waves or particles
