Possible Mars Light in the 5771 - PAGE 3

This is the TOP of the light showing the location of the Mars TAG it has the model and serial number on it.

This shows the possible back view of the light with the cover ON which can be removed by first unscrewing the bolt (or knob) at the center of the back cover (circled in RED). It also shows a lower knob (also circled in RED) which clamps the light agains the headlight opening. If this knob is unscrewed slightly, it will allow the mechanism to lean back for service or access to the parts if needed (and Photos if needed). It was necessary to replace the bulbs from inside the locomotive while in route.

This photo shows the Gearbox of the light. It has 4 holes for mounting onto the Back Plate of the Mars Light. The motor is bolted to the side of this gearbox. Both linkages are mounted on ONE side of the gearbox and in this light, these would be facing towards the TOP of the light.

This photo is of a similar mechanism but the orientation of things is for mounting on the exterior of a locomotive. The motor and gearbox are shown, connected as described above - with the gearbox mounted to the BACK of the light and the motor mounted to the gearbox. The TAG location for identifying the motor data is shown. Both linkages are attached to the PROJECTIONS (as above) facing the gearbox.

This photo shows the SPRINGS at the junction of the 2 bulb rings with the outer oval ring on 1 side. There were 2 per junction for a total of 4.
