LED's will always be more efficient than incandescent, so lower draw on these than the stock almost certainly.
I wonder if I could find one to fit the R3 Touring that has just one big headlight; been playing with the idea of add-on Clearviews but this might be a way to go as well.
I have heard that the Daymakers may be a bit too directional, as in leaning into a corner causes the light to light up all the wrong things and not ahead, but that's just what I read. So may go for a few polished stainless Clearwater Darla's still. More lamps make you more visible too.
