The Ironman 4x4 auto headlights on kit is suitable for 12/24v vehicle systems and autonomously activates the vehicles headlights. Once the key is turned on the lights will come on after a 10 second delay, and will turn off after the key has turned off. This system can be wired into a negatively or positively switch vehicle system. This kit is perfect for vehicles where the headlights can stay on all the time, reducing the chance of a flat battery. There is a built in over ride for when you do want to have the lights on.
