I've swapped over a few bikes over a few years.
The newer LEDs mimic halogens better than the old ones, & other than having to adjust the headlight height after the swap I really haven't had any issues over what's now been thousands of miles.
I went on to swap out all the lights on the SYMs since they're brighter, so more visible. I actually doubled up on the blinkers since the euro/asian blinker locations were already wired. If someone doesn't see the signals on those bikes they are not looking.
The caveats I'll note are that none of the bikes I've swapped use that 35/35 watt one you have, & they can be interesting to fit, there will be a heat sink or a fan, so being mindful of how that will fit and what it may contact are something to consider.
I used a fan cooled option in my current (2018) Burgman vs. the air cooled ones I used in the SYMs since it helped with clearance for instance.
As far as complaints go. Not really. I have gotten flashed a couple times since I swapped the SYMs, but really it's in situations where it was the terrain causing the angle to hit just right, & it would have been that way regardless of what I was riding/driving.
Curious here...
Headlight reflector/buckets which use a Halogen bulb are designed to work with a Halogen bulb.
Apparently there are some new LED bulbs specifically designed to work in a Halogen bucket.
I understand that a lot of guys never, or very rarely, ride in the dark.
If you do ride in the dark - do you get complaints from drivers with your LED bulb in a Halogen reflector?
I have also read that some riders are fully aware that their LED bulb in a Halogen bucket IS blinding drivers - and they state they do not care, because they really like that white, flood-lit area in front of their bikes.
