It says 10 feet coiled cord, but there is no way you can pull that cord 10 feet away from the light and keep it plugged in the cigarette lighter. The most comfortable distance would be 5 feet.I put the light on the very edge of the my car's roof and still can get the cord to stay in the cigarette lighter located in the center of the car, so if you have pickup truck or SUV it would be near impossible without an extension.The light is too small with a very light orange shield, so not very visible during the day.Overall is not a commanding light for freeway work.
