night lite
I've been reading this thread without commenting (that's unusual for me, right?) for some time.
I have to say that I find the light emitted from my twin lights to be quite satisfactory. Last summer I spent some time riding at night (I work all day) and I never felt constrained by the headlights. I did consider the HID retrofit that's in the DK catalog, but I for one don't like a car with HID lamps approaching me. I find the light emitted from a HID lamp to be irritating. The other drawback to HID lighting is the price, somewhere in the 400 buck range for each headlamp.
I may try Pianoman's PIAA lamps this summer or when I have a failure of one of the stock lamps, because, why replace 'em if they are doing a good job, which they are. I did have a problem with the aim when I first got the bike. I was looking for grasshoppers on low beam. A little adjusting cured that along with splitting the beams apart a little more.
I've seen comments elsewhere about fitting a single beam. Personally, I like the twin headlamps. It sets the R3 apart, like a signature, along with the engine. It looks, well, bugeyed.
