A plurality of LEDs may be positioned in a linear array on the exterior assembly and may illuminate in a sequence to communicate the movement of the latch when the latch moves away from a door jamb into a locked position. The plurality of LEDs may also illuminate in a sequence to communicate the movement of the latch when the latch moves toward a door jamb into an unlocked position. Additionally, the plurality of LEDs may also be illuminated in a pattern to communicate when the power level in the battery of the deadbolt lock assembly is low. ## Claims ### Claim 1 A deadbolt lock assembly comprising: a latch for locking and unlocking a door in which the deadbolt lock assembly is engaged; and an exterior assembly in communication with the latch comprising a plurality of LEDs aligned in a linear array located on the exterior assembly, wherein the linear array is oriented substantially parallel to the latch, wherein the linear array has a first end furthest from a door jamb and a second end nearest the door jamb, wherein the plurality of LEDs comprises at least three LEDs that are illuminated in a sequence to indicate a movement of the latch, such that a single LED of the plurality of LEDs is illuminated at each step of the sequence. ### Claim 2 (depends on 1) The deadbolt lock assembly of claim 1, wherein exterior assembly comprises a faceplate and a keyway. ### Claim 3 (depends on 1) The deadbolt lock assembly of claim 1, wherein the plurality of LEDs are evenly spaced apart, and wherein the linear array of the plurality of LEDs is arranged in a horizontal direction. ### Claim 4 (depends on 1) The deadbolt lock assembly of claim 1, wherein the plurality of LEDs comprises five LEDs, wherein a first LED is positioned nearest the first end of the linear array, a second LED positioned next to the first LED towards the second end, a third LED positioned next to the second LED in a center of the linear array, a fourth LED positioned next to the third LED, and a fifth LED positioned nearest the second end. ### Claim 5 (depends on 1) The deadbolt lock assembly of claim 1, wherein the deadbolt lock assembly produces a first audible tone when the latch moves to a locked position and produces a second audible tone when the latch moves to an unlocked position, wherein the first audible tone is different than the second audible tone. ### Claim 6 (depends on 1) The deadbolt lock assembly of claim 1, further comprising a processor, wherein the processor is connected to a power source and the plurality of LEDs, and a non-transitory computer readable medium storing computer readable instructions that, when executed by the processor, causes the processor to at least: authenticate a signal from a wireless device to move the latch to a locked position or an unlocked position; instruct the plurality of LEDs to illuminate in a lock sequence when the signal is to move the latch to the locked position; and instruct the plurality of LEDs to illuminate in an unlock sequence when the signal is to move the latch to the unlocked position, wherein the lock sequence is different than the unlock sequence. ### Claim 7 (depends on 6) The deadbolt lock assembly of claim 6, wherein the lock sequence includes illuminating a first LED of the plurality of LEDs nearest the first end of the linear array and then illuminating a second LED immediately next to the first LED while turning off the first LED after a predetermined time interval. ### Claim 8 (depends on 6) The deadbolt lock assembly of claim 6, wherein the unlock sequence includes illuminating a first LED of the plurality the LEDs nearest the second end of the linear array and then illuminating a second LED immediately next to the first LED while turning off the first LED after a predetermined time interval. ### Claim 9 A deadbolt lock assembly comprising: a latch for locking and unlocking a door in which the deadbolt lock assembly is engaged; and an exterior assembly in communication with the latch comprising a plurality of LEDs aligned in a linear array located on the exterior assembly, wherein the linear array is oriented substantially parallel to the latch, wherein the linear array has a first end furthest from a door jamb and a second end nearest the door jamb, wherein the plurality of LEDs are illuminated in a sequence that moves in the same direction as a movement of the latch when the latch moves to either a locked position or an unlocked position such that two LEDs of the plurality of LEDs are illuminated at each step of the sequence. ### Claim 10 (depends on 9) The deadbolt lock assembly of claim 9, wherein exterior assembly comprises a faceplate and a keyway. ### Claim 11 (depends on 9) The deadbolt lock assembly of claim 9, wherein the plurality of LEDs are evenly spaced apart, and wherein the linear array of the plurality of LEDs is arranged in a horizontal direction. ### Claim 12 (depends on 9) The deadbolt lock assembly of claim 9, wherein the plurality of LEDs comprises five LEDs, wherein a first LED is positioned nearest the first end of the linear array, a second LED positioned next to the first LED towards the second end, a third LED positioned next to the second LED in a center of the linear array, a fourth LED positioned next to the third LED, and a fifth LED positioned nearest the second end. ### Claim 13 (depends on 9) The deadbolt lock assembly of claim 9, wherein the deadbolt lock assembly produces a first audible tone when the latch moves to the locked position and produces a second audible tone when the latch moves to the unlocked position, wherein the first audible tone is different than the second audible tone. ### Claim 14 (depends on 9) The deadbolt lock assembly of claim 9, wherein the plurality of LEDs illuminate in a lock sequence when the latch moves to the locked position, wherein the lock sequence includes illuminating a first LED and a second LED of the plurality of LEDs nearest the first end of the linear array and then illuminating a third LED of the plurality of LEDs immediately next to the second LED while turning off the first LED after a predetermined time interval. ### Claim 15 A deadbolt lock assembly comprising: a latch for locking and unlocking a door in which the deadbolt lock assembly is engaged; and an exterior assembly in communication with the latch comprising a plurality of LEDs aligned in a linear array located on the exterior assembly and are oriented substantially parallel to the latch, wherein the linear array has a first end furthest from a door jamb and a second end nearest the door jamb, wherein the plurality of LEDs comprises at least three LEDs that are illuminated in a sequence to indicate a movement of the latch, wherein the deadbolt lock assembly produces a first audible tone when the latch moves to a locked position and produces a second audible tone when the latch moves to an unlocked position, wherein the first audible tone is different than the second audible tone. ### Claim 16 (depends on 15) The deadbolt lock assembly of claim 15, wherein the plurality of LEDs illuminate in a lock sequence when the latch moves to the locked position, wherein the lock sequence includes illuminating a first LED of the plurality of LEDs nearest the first end of the linear array and then illuminating a second LED of the plurality of LEDs immediately next to the first LED after a first predetermined time interval. ### Claim 17 (depends on 16) The deadbolt lock assembly of claim 16, wherein the lock sequence further includes illuminating a third LED of the plurality of LEDs immediately next to the second LED after a second predetermined time interval, until all of the plurality of LEDs are illuminated. ### Claim 18 (depends on 15) The deadbolt lock assembly of claim 15, wherein the plurality of LEDs illuminate in an unlock sequence when the latch moves to the unlocked position, wherein the unlock sequence includes illuminating a first LED of the plurality of LEDs nearest the second end of the linear array and then illuminating a second LED of the plurality of LEDs immediately next to the first LED after a first predetermined time interval. ### Claim 19 (depends on 18) The deadbolt lock assembly of claim 18, wherein the unlock sequence further includes illuminating a third LED of the plurality of LEDs immediately next to the second LED after a second predetermined time interval, until all of the plurality of LEDs are illuminated. ### Claim 20 (depends on 15) The deadbolt lock assembly of claim 15, further comprising a processor, wherein the processor is connected to a power source and the plurality of LEDs, and a non-transitory computer readable medium storing computer readable instructions that, when executed by the processor, causes the processor to at least: authenticate a signal from a wireless device to move the latch to the locked position or the unlocked position;
