     As shown in  FIGS. 4 and 5A-5E , the integrated side light water dispenser module  200  is configured as an internal water dispenser  300  completely integrated into a light module such as a side wall light module. The integrated side light water dispenser module  200  includes a housing  202  (which is foamed in place in a side wall inner liner  212  (see  FIG. 3 ) of the refrigerator appliance  100  and is therefore also referred to as a foamed-in housing  202 ), a light emitting diode (LED) in the form of an LED strip  204  having a plurality of LEDs  205  over the length of the LED strip  204  which in turn extends over substantially an entire length of the foamed-in housing  202  (see  FIGS. 5A and 5B ). The LED strip  204  is positioned next to a light diverter and dispenser housing  206  which in turn is covered by a light diffuser  208 . A water line WL is disposed in the foamed-in housing  202  and is configured to pass through an opening at the top of the foamed-in housing  202 . A dispenser cover  310  is also visible in  FIG. 4 . A description of the assembly of the integrated side light water dispenser module  200  to, for example, the side wall inner liner  212  of the refrigerator appliance  100  will now be provided starting with the assembly of the foamed-in housing  202  of the side light water dispenser module  200  to the insulated side of the side wall inner liner  212 . 
     As shown in  FIGS. 6A and 6B , the foamed-in housing  202  is first assembled to the insulated side of the side wall inner liner  212  of the refrigerator appliance  100  through a cutout C formed in the side wall inner liner  212 . A water guiding conduit WG is then assembled to the top of the foamed-in housing  202 . An electrical line or wire EL having an electrical connector EC on an end thereof is fed from the top and bottom (the top one being shown in  FIG. 6B ) of the foamed-in housing  202 . Insulation is then added to the refrigerator appliance  100 , so as to permanently fix the foamed-in housing  202  and water guiding conduit WG in the side wall inner liner  212  of the refrigerator appliance  100 . 
     As shown in  FIGS. 7A and 7B , after the insulating process has finished, the water line WL is routed through the water guiding conduit WG and comes through the top of the foamed-in housing  202 . 
       FIGS. 8A and 8B  show the assembly of the LED strip  204  with LEDs  205  to the foamed-in housing  202  of the side light water dispenser module  200 . In particular, after the water line WL has been routed into the foamed-in housing  202 , the LED strip  204  is assembled to the foamed-in housing  202 . The LED strip  204  is connected from the bottom connector via the electrical wire W and the LED strip  204  is then snapped into a side recess R in the foamed-in housing  202  (see  FIG. 8B ). 
       FIGS. 9A, 9B, and 9C  show the assembly of the light diverter and dispenser housing  206  to the foamed-in housing  202  of the side light water dispenser module  200 . In particular, after the LED strip  204  is assembled, the light diverter and dispenser housing  206  is then assembled. The light diverter and dispenser housing  206  is placed in the foamed-in housing  202  and secured with a fastener such as, for example, one screw (not shown). The geometry of the light diverter and dispenser housing  206  creates the water line guiding conduit for the water line WL through the side light water dispenser module  200 . The electrical line or wire EL and electrical connector EC are also protected in the space created. 
       FIGS. 10A and 10B  show the assembly of the light diffuser  208  to the foamed-in housing  202  of the side light water dispenser module  200 . In particular, after the light diverter and dispenser housing  206  is assembled, the light diffuser  208  is assembled. The light diffuser  208  is stuck to the light diverter and dispenser housing  206  by, for example, an adhesive or adhesive tape. The light diffuser  208  can be made of, for example, glass or plastic. The light diffuser  208  is divided into an upper piece  208 A and a lower piece  208 B, with the space where the dispenser cover  310  is to be located being provided therebetween. 
       FIG. 11  shows an enlarged view of where the water dispenser  300  (see  FIGS. 4 and 12 ) is assembled to the light diverter and dispenser housing  206  of the side light water dispenser module  200 .  FIG. 12  shows some of the main parts of the water dispenser  300  according to an exemplary embodiment consistent with the present disclosure. In particular, the water dispenser  300  includes an activation unit  302 , an activation housing  304 , an activation paddle  306 , an activation switch  308 , the dispenser cover  310 , and a water line nozzle  312 . 
     As shown in  FIGS. 13A and 13B , the activation unit  302  is first connected to the electrical connector EC (see  FIG. 6B ) from the top and the water line WL is routed through the center of the activation housing  304 . The activation unit  302  is then assembled to the side light water dispenser module  200  by being snapped into the light diverter and dispenser housing  206  (see  FIG. 13B ). 
       FIGS. 14A and 14B  show the assembly of the water line nozzle  312  to the water line WL and to the activation unit  302 . In particular, the water line nozzle  312  is pushed onto the end of the water line WL and snapped into the activation unit  302  (see  FIG. 14B ). The water line nozzle  312  secures the water outlet in the correct position in the water dispenser  300 . 
       FIGS. 15A and 15B  show the assembly of the water dispenser cover  310  into the light diverter and dispenser housing  206 . In particular, the dispenser cover  310  is assembled into the light diverter and dispenser housing  206  by, for example, snapping it into position in the light diverter and dispenser housing  206  so as to substantially cover the water dispenser  300  except for the water line nozzle  312  and activation paddle  306 . 
       FIG. 16  shows the completed assembly of the side light water dispenser module  200  to the side wall inner liner  212  according to an exemplary embodiment consistent with the present disclosure. As seen from  FIG. 16 , the water dispenser  300  is disposed between the upper piece  208 A and the lower piece  208 B of the light diffuser  208 . 
       FIGS. 17A and 17B  show the paddle activation of the water dispenser  300  using a drinking glass DG to press the activation paddle  306  to fill the drinking glass DG. More specifically, after opening the door  103 , the user reaches inside the fresh food compartment  102  and presses the drinking glass DG against the activation paddle  306  (see  FIG. 17B ). This in turn activates the activation switch  308  and opens a water valve (not shown) disposed in the water line WL. Fresh cool water is then fed to the water line nozzle  312  to fill the user&#39;s drinking glass DG. Of course, although a drinking glass DG is shown, any container that is capable of holding water can be used as long as it can fit (a smaller container) under the water dispenser  300  and permit the user to activate the activation paddle  306 . 
       FIG. 18  shows the button activation of the water dispenser  300  by manually pressing or touching an activation button to fill the drinking glass DG. For example, the user can press or touch a front face  311  of the dispenser cover  310  at a location above the water line nozzle  312  to fill the user&#39;s drinking glass DG. In this regard, note that the button activation can allow containers to be filled that are too large or might not otherwise be shaped to be pressed against the activation paddle  306 . Alternatively, a separate and flush button or touch sensitive area could be disposed on the upper part of the front face  311  of the dispenser cover  310 . 
       FIGS. 19A to 22  show various modifications and further embodiments of the side light water dispenser module  200 . For example,  FIGS. 19A, 19B, and 19C  show a further embodiment of the button activation of the water dispenser  300 ′ where a filter status indicator light is included (note that like parts are denoted with like reference numerals but with a prime sign thereafter). More specifically, the front face  311 ′ of the dispenser cover  310 ′ can have a portion FI that is illuminated by LEDs. For example, LEDs and a light pipe can be used. In use, whenever the user dispenses water, the portion FI on the front face  311 ′ will illuminate. The illuminated portion FI will change color to alert the user of their water filter status (e.g., water filter good—white, blue, or green light, water filter near replacement—yellow light, and water filter needs immediate replacement—red light). Also, the fact that the portion FI is illuminated provides a visual indication to the user that the water is dispensing. An indication of when the filter needs to be replaced could also be provided to the user on the front face  311 ′. 
       FIGS. 20A, 20B, and 20C  show a further embodiment of the side light water dispenser module  200 A where a lower LED strip  204 A (behind the lower piece of the light diffuser  208 BA) is controlled to create a filling effect as the drinking glass DG is filled with water (note that like parts are denoted with like reference numerals but with the letter “A” thereafter). More specifically, the lower LED strip  204 A is controlled by individually activating every LED to create a filling effect. For example, if the water valve activates for sixty seconds when the user presses the front face  311 A or presses the drinking glass against the activation paddle  306 A, then the light intensifies as the sixty second time period progresses. At the start, the lowest LED will turn ON and then each LED on the lower LED strip  204 A will turn ON individually and sequentially upwardly over the sixty second time period, thereby showing a filling progress of the water from the water dispenser  300 A filling up the drinking glass DG. This feature gives a visual indication to the user of the activation time interval of the water valve in the water system. 
       FIGS. 21A and 21B  show a further embodiment where a user interface UI is provided in the lower section of the side light water dispenser module  200 ″ where the lower piece  208 B of the light diverter cover was previously provided (note that like parts are denoted with like reference numerals but with a double prime sign thereafter). The upper piece  208 A″ of the light diffuser  208 ″ is the same as before. In this case, the user interface UI can control all functionalities of the refrigerator appliance  100 , as well as any filling features in connection with the water dispenser  300 ″. For example,  FIG. 21B  shows the user interface UI with the temperature set function visible and the refrigeration compartment RC temperature set at 36° F. and the freezer compartment FC temperature set at −2° F. 
     The user interface UI could also display a count while the user is dispensing water into their drinking glass DG. Once the user stops dispensing water, the user interface UI will ask the user if they would like to save this filling time. The user can then name this saved time as a specific container and hit a button (e.g., a touch sensitive button) on the user interface UI to dispense for this particular saved time. For example, if the user dispensed water for 30 seconds, then the UI will ask the user if they want to save this time of 30 seconds. The user can then save this 30 second time as “Jorge&#39;s cup” for future dispensing, thus presenting a customized filling option to the user. 
     The present disclosure offers several advantages over existing internal water dispensing systems. One advantage is the flexibility of having a water dispenser and a light housing share the same space or area inside a refrigerator appliance. The present disclosure also allows for both lighting and water dispenser usability to be optimized within a refrigerator appliance without having to compromise one for the other. Another advantage to the present disclosure is the ability to move the water dispenser and light as close as possible to the front frame of the refrigerator appliance. This will provide the most usable space within the fresh food compartment for the consumer to store food all while providing the consumer with clean water. A technical advantage to the present disclosure is the foamed-in housing and light diverter and dispenser housing form a channel to guide the water line. This reduces the amount of parts in the system and improves the assembly of the sidewall water dispenser. 
     The present invention has substantial opportunity for variation without departing from the spirit or scope of the present invention. For example, while  FIG. 1  shows a single door fresh food compartment-bottom mount freezer style refrigerator appliance  100 , the present invention can be utilized in traditional French door-bottom mount (FDBM) configurations with two doors on top including those having one or more intermediate compartments (such as, but not limited to, pullout drawers) that can be operated as either fresh food compartments or freezer compartments and which are located between the main fresh food compartment and the main freezer compartment, a side-by-side refrigerator where the refrigerator compartment and the freezer compartment are disposed side-by-side in a vertical orientation, as well as in other well-known refrigerator configurations, such as but not limited to, top freezer configurations, bottom freezer configurations, configurations where the entire refrigerator unit is a fresh food compartment from top to bottom without a freezer compartment, panel front type refrigeration and freezer configurations, and the like. Moreover, while the internal water dispenser located in the housing of a side light module  200  has been described with reference to an internal water dispenser  300  located in the housing of a side light module in a side wall of the fresh food compartment  102 , the present disclosure also contemplates other configurations such as, but not limited to, integrating the side light water dispenser module into other parts of the fresh food compartment.
