I wrote the below code

    lights = {}
    @util.Throttle(MIN_TIME_BETWEEN_SCANS, MIN_TIME_BETWEEN_FORCED_SCANS)
    def update_lights():
        'Update    the    WeMo    led    objects    with    latest    info    from    the    bridge.'
        bridge.bridge_update()
        new_lights = []
        for (light_id, device) in bridge.Lights.items():
            if (light_id not in lights):
                lights[light_id] = WemoLight(device, update_lights)
                new_lights.append(lights[light_id])
        if new_lights:
            add_devices(new_lights)
    update_lights()
