My instruction book for the install gives specifications for the generator white wire output. Says it will provide 1/2 amp at 7 1/2 volts. This is way more than enough for a couple of LED headlights. I will go out on a limb and say that is not DC however, so if using a LED lamp you may want to use a rectifier (diode) to make DC out of it as LED's typically have a very low tolerance for reverse voltage. Since there seems to be no real standard for these things your results may vary. I have a few of what Ebay calls Buck Regulator which basically take anything from 3 to 30 volts in and output whatever you set for the output, so I may try that just for fun to get a regulated output for a LED light.
