For some reason the ditchlights on the sd80' and 90's I have do not seem to flash the come on when the units hits a certain speed but then I hit the horn and nothing and this is at 60mph. Is there something wrong here or do I need to do something different?
 
HUH I thought fra mandated all locomotives in North America to have either a mars light or ditchlights? If I want to make them work what would I have to do?
 
FRA only mandated them to be installed and working. Not to flash that`s a select option that was mostly chosen by CSX and NS.
 
There used to be a "Modding with Hack" article at The Erecting Hall website for installing flashing ditchlights to locos. I used it many years ago. It is not listed on the rebuilt site though.
May be worth sending a PM to n8phu to see if he still has it.
Cheers,
Mike
 
That hack is not required to get the ditchlights to flash. There are multiple threads that explain how to easily change the config settings to get the desired effect within this sub-forum.
