I recently upgraded my headlights. I was going to just get the Sunpie set, but found someone selling a used JW Speaker headlight for half price because he traded bikes (SG to RG). I bought the Sunpie passing lamps. Everything installed easily with no need to cut anything or buy extra parts. I had to adjust the headlight down a bit (as all headlights need to be aimed properly), and once adjusted I am very happy with the upgrade. I know someone that has the Sunpie and he is happy with it.
I went Sunpie last year and am happy with it. Much better than the stock headlight. I don't have a touring model so only have one headlight
and no aux/driving light so the Sunpie gave me about double the visibility at night and is much more noticeable during daylight.
