This is probably due to the way Node-RED loads modules. It will generally add them in the order in which it finds them in the flow file, but will try to load any config nodes first. So when you add them in this order - and thus before Node-RED has restarted and rescanned for config nodes (which the dashboard has) - the led node will load first and not find the dashboard as it hasn't loaded yet. On a restart it will find the dashboard config nodes first and thus load that up first - so by the time it loads the led then the dashboard is there.
Thank you very much for the Information I had loaded and re installed my dashboard a number of times when changing from SD card to SSD boot and then doing some other stuff I could have loaded the Led first and never even thought about it.
Thank you all your help everyone
