Something like Baja Designs have it on my FE390 works Fantastic. Lights up street signs at Noon not a joke. But NOT street legal. Their are street legal kits. Go to search (Headlight) you should find some different setups
Im running the Cyclops LED bulb in the stock headlight housing. I had to slightly modify how the LED bulb mounted to the stock housing but it works great. Its not as bright as a Baja Designs setup but it is a hundred times better than the stock bulb. Real happy how it turned out.
