DIY Dual Sport Conversion
Technical Article Sponsor

I converted my dirt bike to a dual sport over the winter. I purchased my dirt bike used and the previous owner had already replaced the stock headlight and taillight pigtails/connectors with the double contact type. This gives High and Low Beam switching for the headlight and Brake and Running/Parking Lights for the taillights.


The previous owner also had a speedometer, turn signal switch, and a horn switch installed.


I installed a hydraulic brake light switch, flush-mount turn signals, horn and a flasher.


Next, I went to the local dollar store and picked up 10 AA size rechargeable batteries at 1.2-volts each which when wired in series gives you 12 volts. Pay attention to how many volts the rechargeable batteries are because some are 1.5-volts in which case you would only need 8. This battery pack keeps the lights operational for the required amount of time to pass vehicle codes. You may want to install a motorcycle battery in place of the rechargeables if you want to be able to leave the lights on for a longer period of time.


I then went to Radio Shack and picked up a full-wave bridge rectifier good for 25-amps.


I have included a wiring diagram below of how I wired my dual sport components. My lights do not flicker at idle and the batteries charge and put out enough power to run the flasher.
