Both of my ST1300's have the Evitek G6 led bulbs in them. On our trip to Colorado I got to see the conspicuous effect of the high beams during the day. Yes, the Harley Ultra in front is on high beam too. I am on the bike in the back and my nephew is on the 06 in the middle. No aux lights. Both my bikes have the flashback leds too.
if you are not happy with the cutoff there is a few things that you can do with the Evitek G6.
if you bend up the metal wing shields a little bit it will flatten out the beam and sharpen the cutoff.
if you add a bit of wire across the bottom to cause the bulb to down tilt it will improve the low beam a bit but it will slightly degrade the high beam focus.
twist the fan to level out each beam.
if you are still not happy post a picture of the pattern on a wall.
The ST1300 has a lot of knobs that you can adjust the alignment of the beam.
I ride a lot at night and the ST1300 with these LEDs are awesome....
