Abstract
Provided are a reading light assembly for a vehicle and a field replaceable unit for an in-vehicle reading light assembly. An embodiment of the reading light assembly for a vehicle includes a housing for attaching the reading light assembly to an interior portion of the vehicle and a field replaceable unit for engaging with the housing. An embodiment of the field replaceable unit includes a power module including a power interface for receiving operational power from a power source, a light module including a plurality of LEDs, and a control module that includes a control interface for receiving a user input signal from a user input device so that the control module can vary a light intensity that is output from the plurality of LEDs according to the user input signal. In some embodiments the reading light assembly and field replaceable unit include a second power interface for receiving power from a secondary power source when the primary power source is interrupted so that the light assembly is operable to function as an in-vehicle emergency light.
