Was going to use 2x projectors beams on my SD last year when I rebuild my pile. The front end met a pick up truck with the PO. The projector lights were back ordered and held up my build over the winter. A bud came up with a stock headlight so I used it.
What I noticed about the projector beams is the small frontal area that is lit for others to see. My Ducati has the projector beams and other riders tell me my lights are off when I am riding, when they are on. Not good for the bule hairs who want to cross my path.
The stock SD and Adventure head light bucket gives a big reflective surface area for head on traffic.
