Quoted from Ed209:
Super helpful, thanks. I just ordered an extra node board as a backup so I’ll swap that in when it arrives to test. Was going to order some extra flasher lamps but can’t seem to find them anywhere online. Contacted Stern to see if I can get one via them. :/
Did you order the node 8 "master" board, or just the node sub board that the lights and flasher are on?
Also the flasher in this case is just a LED diode on a board, not a bulb, so that's why you can't find it.
