WebGLSL Arrays. Each light we have defined (so far) is composed to 4 4-component vectors, ambient, diffuse and specular colour, along with the "position" (direction) vector. If we wanted to provide, for instance, 3 lights of this type, we *could* create 12 different uniform values, and set each of these uniforms individually.
