this is what the hot rod guys do to clean up their rides, was what I was thinking of:

 

that kuryakin set is awesome

 

never drilled glass before... hrrrmmmmmm

 

They are nice, but if I was just looking to get more light out front. I would bite the bullet (cause Harley wants $350 for them, but Chicago HD sells them for about $280) and get the twin headlight off a Fatbob. It uses two complete headlight bulb sets and both function together as low or high beams.




I think those type lights only have a class lens, and drilling into the bottom of yours mount the turn signal bulbs shouldn't present any problems if your light buckets use the more modern (small) bulbs behind a glass or crystal lens. Instead of the older big headlight 5" or 7" lamps.

 

bad cop no donut here

lose those turn sigs take up to much space,
dont worry mine are comin off real soon
as for the 3 lights maybe for a road king or touring bike
your scoot is better than those ooops
