The white lunar aspects on the grade crossing signals indicate the state of the grade crossing. Off means the crossing protection is not engaged or not engaging. Flashing indicates the crossing protection is engaging or disengaging. Solid indicates the crossing protection is fully engaged. By the looks of the video Columbia was fully engaged when the LRV was crossing.
