The lighting device may include a housing, at least one light source such as a light-emitting diode (LED), a rechargeable battery, optionally a microprocessor, and at least one solar panel. The lighting device may include a mount configured to secure the lighting device to a support, such as a frame or other portion of a vehicle or other device. The set of lighting devices may include first and second lighting devices, each including a light source, optionally wherein the light sources may emit different colors of light. ## Claims ### Claim 1 A lighting device, comprising: a housing including a front wall, a back wall, and at least one side wall between the front wall and the back wall; at least one light source facing towards the front wall; a rechargeable battery in electronic communication with the light source; at least one solar panel coupled to the at least one side wall of the housing; the solar panel being in electronic communication with the light source and the rechargeable battery; a magnet extending along an entire width of the housing and coupled to or proximate the back wall for attaching the housing to an outermost wall of a second lighting device, the back wall being planar and configured to abut the outermost wall of the second lighting device; and a mount coupled to or integrated into the housing, the mount being configured to secure the lighting device to a support with a flexible strap, wherein the mount includes a first hook and a second hook for securing the strap therebetween, wherein when the mount is coupled to the housing, the first hook faces in a direction towards the front wall and the second hook faces in a direction towards the back wall; wherein the lighting device is configured to transfer power from the rechargeable battery to the second lighting device when the second lighting device is attached to the housing along the back wall via the magnet. ### Claim 2 (depends on 1) The lighting device of claim 1, wherein the mount further comprises the strap, a first end of the strap coupled to the first hook and a second end of the strap coupled to the second hook. ### Claim 3 (depends on 1) The lighting device of claim 1, wherein the housing includes a plurality of side walls, and the mount is coupled to or integrated into a side wall different than the side wall to which the solar panel is coupled. ### Claim 4 (depends on 3) The lighting device of claim 3, wherein the housing includes four side walls, and the solar panel is coupled to a side wall opposite the side wall coupled to or integrated with the mount. ### Claim 5 (depends on 1) A set of lighting devices comprising the lighting device of claim 1, wherein the lighting device is a first lighting device, the set of lighting devices further comprising: the second lighting device including: a housing including a front wall, a back wall, and at least one side wall between the front wall and the back wall; at least one light source facing towards the front wall; a rechargeable battery in electronic communication with the light source; and at least one magnet coupled to or proximate the back wall; wherein the back wall of the second lighting device is the outermost wall configured to abut the back wall of the first lighting device; and wherein the magnet of the first lighting device is complementary to the magnet of the second lighting device, such that the back wall of the first lighting device is releasably attachable to the back wall of the second lighting device by magnetic attraction. ### Claim 6 (depends on 5) The set of lighting devices of claim 5, wherein the second lighting device does not include a solar panel. ### Claim 7 (depends on 5) The set of lighting devices of claim 5, wherein the first lighting device is configured to charge the rechargeable battery of the second lighting device when the first and second lighting devices are coupled together. ### Claim 8 (depends on 5) The set of lighting devices of claim 5, wherein the mount of the first lighting device is a first mount, the set of lighting devices further comprising a second mount that includes at least one magnet, the second mount being releasably attachable to the back wall of the second lighting device by magnetic attraction; and wherein the second mount includes an extension and a flexible strap for securing the second lighting device to a support, the second mount having a width greater than a width of the second lighting device.
