Light Flow didn't work for me. But I did find line where I can change value. I think it will work sync there is no problem with led notifications on Revolution HD 7.0
Can someone correct me if I'm wrong.
system/costumize/acc/ default.xml.
<item type="integer" name="NMS_feature_led_flash_timeout">5</item>
</app>
Change the value to 0, will flash until dismissed
