Abstract: Roading lamp assemblies for use on a construction machine are typically mounted to a frame assembly or similar structure. During operation of the construction machine, the roading lamp assembly experiences vibration which may damage an illuminating apparatus therein. The present invention includes utilization of inner and outer resilient members on either side of a housing assembly which is secured to the frame through a plate member and bolts. The plate member has a plurality of legs which extend through a plurality of mounting holes in the housing assembly, the inner and outer resilient members and the frame. The pair of resilient members are pre-loaded through adequate torqueing of the bolts in cooperation with the plurality of legs to protect the illumination apparatus from damage during extreme vibration. Additionally, a harness assembly which supplies electrical energy to a lamp in the roading lamp assembly passes internally through the frame to an interior chamber in the housing assembly.
