In accordance with some implementations of the disclosed subject matter, systems for projecting light to indicate a device status are provided, the systems comprising: a hardware processor that: determines a light status; determines whether to turn a light source on; selects a light format corresponding to the light status; projects light of a light source according to the light format; and determines whether to turn the light source off. ## Claims ### Claim 1 A media content streaming device for projecting light to indicate a device status, the system comprising: a light source; and a hardware processor that is programmed to: determine a light status indicating a device status of the media content streaming device; identify a first direction that the light source is to be projected; cause light of the light source to be projected in the first direction according to the light status; determine whether the light of the light source is to be turned off based on the device status of the media content streaming device; and in response to determining that the light of the light source is not to be turned off, cause the light of the light source to be projected in a second direction that is different from the first direction. ### Claim 2 (depends on 1) The device of claim 1, wherein the light status includes a light color. ### Claim 3 (depends on 1) The device of claim 1, wherein the hardware processor is further programmed to receive user configuration settings, wherein the light status is determined based on the user configuration settings. ### Claim 4 (depends on 1) The device of claim 1, wherein the hardware processor is further programmed to determine whether the light of the light source is to be turned on in response to determining the light status indicating the device status of the media content streaming device. ### Claim 5 (depends on 1) The device of claim 1, wherein the hardware processor is further programmed to determine whether the light of the light source is to be turned on based on a detection of a user in proximity to the media content streaming device. ### Claim 6 (depends on 1) The device of claim 1, wherein determining whether the light of the light source is to be turned off is based on determining whether the device status of the media content streaming device has changed. ### Claim 7 A method for projecting light to indicate a device status of a media content streaming device, comprising: determining a light status indicating a device status of the media content streaming device; identifying a first direction that the light source is to be projected; causing light of the light source to be projected in the first direction according to the light status; determining whether the light of the light source is to be turned off based on the device status of the media content streaming device; and in response to determining that the light of the light source is not to be turned off, causing the light of the light source to be projected in a second direction that is different from the first direction. ### Claim 8 (depends on 7) The method of claim 7, wherein the light status includes a light color. ### Claim 9 (depends on 7) The method of claim 7, wherein the method further comprises receiving user configuration settings, wherein the light status is determined based on the user configuration settings. ### Claim 10 (depends on 7) The method of claim 7, wherein the method further comprises determining whether the light of the light source is to be turned on in response to determining the light status indicating the device status of the media content streaming device. ### Claim 11 (depends on 7) The method of claim 7, wherein the method further comprises determining whether the light of the light source is to be turned on based on a detection of a user in proximity to the media content streaming device. ### Claim 12 (depends on 7) The method of claim 7, wherein determining whether the light of the light source is to be turned off is based on determining whether the device status of the media content streaming device has changed. ### Claim 13 A non-transitory computer-readable medium containing computer-executable instructions that, when executed by a processor, cause the processor to perform a method for projecting light to indicate a device status of a media content streaming device, the method comprising: determining a light status indicating a device status of the media content streaming device; identifying a first direction that the light source is to be projected; causing light of the light source to be projected in the first direction according to the light status; determining whether the light of the light source is to be turned off based on the device status of the media content streaming device; and in response to determining that the light of the light source is not to be turned off, causing the light of the light source to be projected in a second direction that is different from the first direction. ### Claim 14 (depends on 13) The non-transitory computer-readable medium of claim 13, wherein the light status includes a light color. ### Claim 15 (depends on 13) The non-transitory computer-readable medium of claim 13, wherein the method further comprises receiving user configuration settings, wherein the light status is determined based on the user configuration settings. ### Claim 16 (depends on 13) The non-transitory computer-readable medium of claim 13, wherein the method further comprises determining whether the light of the light source is to be turned on in response to determining the light status indicating the device status of the media content streaming device. ### Claim 17 (depends on 13) The non-transitory computer-readable medium of claim 13, wherein the method further comprises determining whether the light of the light source is to be turned on based on a detection of a user in proximity to the media content streaming device. ### Claim 18 (depends on 13) The non-transitory computer-readable medium of claim 13, wherein determining whether the light of the light source is to be turned off is based on determining whether the device status of the media content streaming device has changed.
