So another bug in TRS19 (go figure).  It appears that currently if I make a new route, and place an engine, and then go into driver mode, the headlights don't work.  Close out and go into a route that existed before the last update, lights work fine, even if its the same engine that I tried in the new route.  Doesn't seem to matter who made the engine i.e. JR, RRMODS, or someone else, none of them work.
