Using layer visibility in active render layer makes more accurate preview but can cause problems in some cases: https://developer.blender.org/rB1973b17fce65a4dfececb45b19abec37898c1ab5#comment-1 GLSL lamps now ignore layer visibility if lock_camera_and_layers is OFF or game engine is running. The material lamp group still works unconditionally though.
