11. A warning device for a highway-rail grade crossing, said device comprising:
-
a signal assembly comprising a support structure, a first signal lamp, and a second signal lamp, said support structure including a mast, wherein the first and second signal lamps are attached to the mast for elevation of the first and second signal lamps above a ground level proximate a railroad crossing; and an alignment apparatus coupled to the signal assembly, said alignment apparatus comprising a source for casting electromagnetic energy on the first signal lamp and/or on the second signal lamp and a detector for sensing the electromagnetic energy cast on said first signal lamp and/or second signal lamp, said source and said detector being oriented so that the electromagnetic energy cast on the first signal lamp and/or on the second signal lamp and detected by the detector is indicative of an alignment or orientation of the signal assembly; and a control unit communicatively coupled to the alignment apparatus, wherein said control unit is configured to receive a signal from the alignment apparatus relating to the electromagnetic energy cast by the source and/or detected by the detector, said control unit being configured to generate data indicative of the alignment or orientation of the first signal lamp and/or the second signal lamp using the signal received from the alignment apparatus.
