Headlights are constant on, fixed orientation. It has dim and bright.
The ditch lights are on, and flash for horn blow, station arrival, etc... they are sometimes turned off to avoid being blinding.
The red marker lights are off in forward, if the unit were in push mode, they would be illuminated. This can be done by wiring the markers to the rear headlight, or you can just skip wiring the markers and leave unpowered LEDs in the holes.
The eyebrow strobes were only on the P40s (the 800 series) and were extremely short lived because they were blinding to the cab crew. Unless you have a fade stripe 800 series, remove them. If you want them to work, then they both would strobe simultaneously. If you have a P42, then they eyebrow strobes and the red stop light between the windows shouldnt even be there.
