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.
