I'v replaced all the lights on my 2012 Blue FJR with LED. (the lone exception of the rear license plate light!)
(Please see the search text below if you want to know what brand I used.)
(search on Amazon...)
HIKARI H4/9003 LED Headlight bulbs, New Gen of Japanese CSP LED Tech, Adjustable Beam, Easy install, 10000lm 6K Cool White IP68
This is all anecdotal, but I'm happy with the lights. I do recall having to cut away some of the rubber boot behind the light to accomodate the longer, bigger, LED bulb. The best cut would leave that boot snug on the rear of the light.
Adjusting after: I found myself at a strip mall in a parking space facing a large, plate glass, window. A Ha! I could see both headlights, lit up, and each cast a very particular pattern on the glass. I sat there and adjusted both lights until both refelections were identical reasoning that the UP/Down tilt would have to be the same for each that way.
Later, I went out on a back road with no street lights and rode up and back many times adjusting the lights. I turned those nobs up/down as needed one full rotation EACH every time. I figured they'd stay in sync if I made the same adjustment (one full turn) to both lights every time.
Zen: The lights make a wide "bar" shape across the road with a dark space above and below. The horizontal line between light and dark was even and level, so I'd like to believe the headlights had the same up/down tilt.
I like to see just a little "dark space" above the "Bar" (on dim) in the road so that I know the lights aren't shining in the eyes of oncoming cars. (Some things you have to learn by DOING not reading.. light adjustment is one of them..that's zen.)
Empirical test: lastly , ride the same road (no street lights) when there is oncoming traffic.... many times. Observe the cars. Does Each and every car flash his headlights? If so, your lights are too high. My goal was to have an acceptable forward cast pattern as far out as I could WITHOUT other driver's flashing me to say my lights were too bright. My "fine" adjustment were full half turns of each knob.
NB: read the instructions on how to level the beam by twisting the lights right and left as you seat them. That bit is important.
I hope this will help someone. Please forgive me for pointing out things you probably already know!
