The difference between afloodlight and a spotlight:* A spotlight has a narrow beam that concentrateslight on a small area.* A floodlight is built so that the light spreads overa wide area.* With a spotlight you will see things further away infront of you however it will leave everything beside you in the dark with afloodlight the reverse is the case.* Because the light is more concentrated， a spotlight willappear brighter than a floodlight but only within its narrower beam. Aspotlight is more suited to illuminating objects and a floodlight is moresuited to illuminating areas.Application:offroad vehicle， ATVs， truck， engineering vehicles (excavator，treedozer， road roller， bulldozer， crane and mining truck etc.) ，special vehicle(fire engine， police cars， rescue vehicle， communication vehicle， militarycommand vehicle) forklift， trains， boat， bus and tanks.Work/Spot/Day/Fog lamp，Available in the auxiliary lamp for， SUV's bumper， fire engine，ambulance and carIndoor & Outdoor usesWork/Spot/Day/Fog Available for Truck，SUV's bumper; Work light， fire engine，ambulance; Farming， mining， forklift， exterior lighting; Excavator， off-road， and Heavy Duty Equipment.Application: Available for offroad vehicle， atvs， truck， engineering vehicles(excavator， treedozer， road roller， bulldozer， crane and mining truck etc.)， special vehicle(fire engine， police cars， rescue vehicle， communication vehicle， military command vehicle)forklift， trains， boat， bus， and tanks.Back up lightOff Road LightingTruck， Trailer Interior & Exterior LightingConstruction LightingGarden， Backyard LightingBoat LightPackage contains:1 * LED Car LightNote: just the strap， not include the camera and others as shown in the following pictu
