I got one of these Daymakers with VTX adapter from BYAS.
It's very bright! And a lot more visible to cagers even in daytime.
It is not adjustable. This was a problem for me as I have the longer goldwing
fork springs which raises the front a bit. I found some weather stripping
and put on the adapter ring along the bottom to push the bottom of the
daymaker back into the shell. This lowered the beam to where it should be for me.
One other issue these have is due to the nature of the sharp cutoff of the beam,
when cornering there is not a lot of light ahead of you while banked. My two driving lights
on either side of the headlight resolve this easily by aiming them where needed.
All in all, I would wholeheartedly recommend this headlight. It uses much less power
than stock and is much brighter. Long range visibility at night on the highway is outstanding!
Plus it looks cool
