Happen to buy a dirtbike with an old Electrosport Dual Sport kit installed? Still own a bike with Dakar it on it? Trying to figure out why the hell there is a circuit board installed your headlight!? Alot of people were left stranded when Electrosport Industries went out of business in 2010, and there was no info or support on fixing these dual sport kits. While they are still around they no longer build or support Dual Sport kits, so I’m hosting here all of the PDF fitting instructions for various Dakar and other dual sport kits, I hope these can help you keep your old bike’s lighting working for awhile longer!
