Have you done the conversion ?
We started doing them with sealed beams and those dumb festoon lamps .
We would break out the old lamp, drill the metal a bit to fit the new lamp, and put a slimmer regular or halogen lamp in to save $20-$50 on a sealed beam and make the lamp replaceable .
Those Honda motorcycle headlights are expensive.
Some times you have to epoxy the new lamp and socket in . .
Depends on the lamp you buy or get from the junk yard. .
Once we got a few under our belts , the led prices started coming down , making it worth while.
I am trying to make this as simple as I can so the average guy can do this for about $10 and all they need are a few easy to obtain parts .
