A system for determining alignment of a signal includes a light assembly comprising a light source operated by an electronic circuit, a first position sensor configured to measure a geographical direction of the light assembly, a second position sensor configured to measure a tilt angle of the light assembly, and a light communication device configured to receive measurements of the first position sensor and the second position sensor, and wherein the light communication device is configured to evaluate the measurements and determine alignment of the light assembly based on predefined tolerance thresholds for the geographical direction and tilt angle.

An adjustable mount for a light signal assembly may comprise a fixture and a mounting track. The fixture may be configured to be attached to the light signal assembly. The mounting track may be configured to allow the fixture to be adjustably positioned in a direction substantially parallel to a length of a cantilever or bridge and mounted to the mounting track.

A support frame is disclosed for a temporary signal for a railroad. The railroad includes a track having two elongate rails, and the support frame comprises a post arranged to support a railroad signal, a base joined to the post, and at least one attachment for attaching the base to both rails of the track. The base comprises a first beam and a second beam, and the first beam and the second beam are each arranged to be attached to both of the rails.

A mounting arrangement (100) includes an attachment member (102) for attachment to an end of a post (114), a connecting member (104) coupled to the attachment member (102), and a plurality of fastening elements (110) coupling the connecting member (104) to the attachment member (102), each fastening element (110) comprising a longitudinal axis (110A), longitudinal axes (110A) of the plurality of fastening elements (110) being substantially parallel to each other. The connecting member (104) is coupled to the attachment member (102) in a direction defined by the longitudinal axes (110A) of the plurality of fastening elements (110), wherein the attachment member (102) and the connecting member (104) comprise mating cylindrical surfaces (118, 140) which allow a tilting motion of the connecting member (104) about a rotating axis which is perpendicular to the longitudinal axes (110A) of the plurality of fastening elements (110).

Examples of the disclosure enable a signal device to be securely coupled to a post. A post-mount teeter includes a stand including a first body, a first flange extending from the first body, and a platform coupled to the first body, and a base including a second body coupled to the first body, a housing coupled to the second body, a second flange extending from the housing, and a sleeve selectively moveable within a cavity defined by the housing to adjust a distance between the sleeve and the housing. Aspects of the disclosure provide for a teeter system that may be used to present signals to one or more users approaching a signal device from one or more directions.
