If my surge protector has a ground light, should it be illuminated (green)?

Yes. The ground indicator light should be illuminated. If the light is not illuminated, there is a problem with the AC outlet into which the CyberPower surge suppressor is plugged. If this is the case, please disconnect the surge suppressor until the problem is resolved. The problem must be resolved before the CyberPower surge suppressor can be used.
