My kids have one of those John Deere Gator power wheel things. They like to drive it around in our back yard. I have always thought it would be cool to make LED head lights for it, so today I finally had some time to give it a shot. Now, I only built one head light so far, as a test. I may add a second head light some other time. The Gator has plastic head light lenses, but behind them is just a reflective piece of cardboard. So I went through my spare flash light parts and came up with a spare Cree XR-E P4 bin LED, an aluminum heat sink to mount the LED on, which then screws into a reflector. I used a LED driver circuit that powers the LED at 800mA. I wired all this to a 3xAAA battery holder (holds 3 AAA batteries), and wired a push button clicky switch from a broken flashlight (press the button, it clicks, flashlight stays on, click it again, flashlight goes off). So drilled a 1 inch hole behind the Gator's headligt lens, mounted the LED with reflector in it, I had put on a good foot and a half of wire so I could mount the switch under the dash board so the kids can turn the headlight off and on. Well, it all works. Now I need to look into building a second one. I may find a larger battery pack to power both of them from. So now my kids can drive around in the dark. :)
