Some embodiments also may have a solar panel and/or batteries for providing electrical power to LED lights of the light tower which require significantly less electrical power than prior art designs. Some embodiments may not have generators, but many will. ## Claims ### Claim 1 A hybrid light tower comprising: a housing supported on an axle having wheels, said housing supporting a connector receiving 120V AC from external to the housing; a generator supported by the housing; a plurality of LED lights connected to the housing; and a relay which selectively provides AC power to the LED lights from one of the connector and the generator. ### Claim 2 (depends on 1) The hybrid light tower of claim 1 further comprising batteries, said batteries located in the housing and connectable through a DC to AC converter to provide electrical current to the LED lights. ### Claim 3 (depends on 2) The hybrid light tower of claim 2 further a comprising battery charger supported by the housing, said battery charger at least selectively coupled to the connector in a shore power charge configuration with said battery charger in electrical communication with the connector. ### Claim 4 (depends on 3) The hybrid light tower of claim 3 wherein the relay provides an open configuration preventing the back flow of electricity to either of the generator and to the connector. ### Claim 5 (depends on 3) The hybrid light tower of claim 3 further comprising a solar panel supported by the housing and in at least selective electrical communication with the batteries for charging the batteries. ### Claim 6 (depends on 1) The hybrid light tower of claim 1 wherein the relay preferentially selects the connector for providing AC power to the LED lights. ### Claim 7 (depends on 1) The hybrid light tower of claim 1 further comprising a fuel tank supported by the housing providing fuel to the generator. ### Claim 8 (depends on 7) The hybrid light tower of claim 7 wherein the fuel tank and generator are at least partially located within the housing. ### Claim 9 (depends on 1) The hybrid light tower of claim 1 further comprising an on/off switch for selectively providing electricity to the LED lights. ### Claim 10 (depends on 1) The hybrid light tower of claim 1 wherein the LED lights are supported by a boom operably coupled to the housing above the housing. ### Claim 11 A hybrid light tower comprising: a housing supported on an axle having wheels, said housing supporting a connector receiving 120V AC from external to the housing; a solar panel supported by the housing; a plurality of LED lights connected to the housing; and a relay which selectively provides AC power to the LED lights from one of the connector and from a DC to AC converter providing power from a source in at least selective electrical communication with the solar panel. ### Claim 12 (depends on 11) The hybrid light tower of claim 11 further comprising batteries and a battery charger, said solar panel directing DC power to the battery, and said battery directing power through the DC to AC converter to the LED lights. ### Claim 13 (depends on 12) The hybrid light tower of claim 12 further comprising an on/off switch located between the lights and the DC to AC converter. ### Claim 14 (depends on 11) The hybrid light tower of claim 11 further comprising an AC to DC converter supported by the housing which directs DC power through the charger to the battery from the connector in a shore power charging configuration. ### Claim 15 (depends on 11) The hybrid light tower of claim 11 further comprising a generator supported by the housing, said generator selectively connectable by a relay which selects which of the connector and the generator to provide power to the LED lights. ### Claim 16 (depends on 15) The hybrid light tower of claim 15 further a fuel tank supported by the housing. ### Claim 17 (depends on 16) The hybrid light tower of claim 16 wherein the fuel tank and the generator are located within the housing. ### Claim 18 (depends on 11) The hybrid light tower of claim 11 further comprising a boom supporting the LED lights cantilveredly above the housing. ### Claim 19 (depends on 11) The hybrid light tower of claim 11 wherein the solar panels are connected to an exterior upper surface of the housing. ### Claim 20 (depends on 11) The hybrid light tower of claim 11 wherein the relay at least assists in connecting two AC sources simultaneously.
