Ok so this is the Larsen high /low iie two level led tractor light as powered by as I've said the only way I know how to make this stuff work ie floated 12 v coil ( hpi mini here but I get exactly the same with a kinetic floated light coil on my y grande. ) Fed on this bike Into a two wire trailtech to a silicon rectifier from what used to be RadioShack. Two wire dc respecting the POS /neg clearly labeled on the Larsen light.
It's nice looking light that has a pretty nice in adulterated soft field that is great for moderate speeds in the dark.
I have an equally bright led set up on my Puch using Chinese motorcycle led bulb with a built in fan painstakingly into a hollowed out cev bulb but why all the effort. The Larsen is a plug and play if you give it DC and know what's positive and what's neg. So yea it's a wiring project.
