Here are the promised light pattern comparisons for the Nighteye H4 LED headlamps mentioned above.
This is in my V-Strom. A bit of explanation is needed here.
The V-Strom is known for having great headlights -- there are large twin H4 headlights that do a much better job than most motorcycles of lighting up the road. On my Vee (2002 DL1000), I've replaced the left bulb (closest to the centerline of the road) with a 2500 degree yellow bulb -- "
Nokya Hyper Yellow". The right bulb is a normal H4 white bulb (up until I replaced it with the LED). My main reason for this unusual setup is increased visibility, and it seems to work. My theory was that the odd combination would be more likely to be noticed that a single white bulb or two white bulbs. If you see this coming, your brain goes "huh, that's weird". And that's exactly what several people have said to me, to which I say "thanks for noticing me!".
This theory seems to hold up quite well in practice -- I commute daily by motorcycle, and "no-see-um" events are dramatically lower when I'm riding the Vee.
I've also noticed after riding for a few months with this setup that I seem to be a little more aware of where things are in space and how they're moving. I think when something is lit by the unusual yellow color of the left bulb (as well as the white bulb on the right), my brain has learned to form a more precise idea of where it is because it knows exactly where the light is coming from -- I know it's not lit by a car behind me or a street light.
When I switched to an LED bulb on the right, I was hoping that the color contrast would be even more pronounced, and that the added lighting would also aid my ability to see. So far, I've been very happy with the results on both counts.
OK, on to some photos. Here's a shot of the front of the bike in the daytime in front of my office running with the headlights on. LED on the bike's right, yellow Nokya on the bike's left. Pretty striking, even in the daytime.
Here's an uncorrected "before" shot. Both headlights, both incandescent, hitting my garage door (normally a very pale yellow, very nearly white). The overall effect in person is FAR less yellow than this -- the yellow bulb threw the white balance in my phone's camera WAY off. I'm at an angle, but you can get the idea that it's a nice even light pattern with a good cutoff.
In this shot, I've simply unplugged the yellow headlight. This is now just one headlight, the white incandescent H4 on the right. Again, this is uncorrected, but the phone's white balance still went far too yellow, although overall brightness is pretty true-to-life. Still a nice light pattern, no?
Here I've installed the white LED bulb on the right in place of the incandescent. (Yellow bulb on left is still unplugged) Note how much brighter it is, but the pattern is the same. Cutoff is in the same place, and bright spot in the same place. White balance is pretty good, too (the phone's flash is an LED, so I suspect the camera calibrated around LED illumination). This shot gives a pretty realistic idea of what it looks like in real life and what the difference in brightness is. I just noticed that my motion sensing light above the garage came on, and the sky got a little darker (I was doing this right at dusk, so there's a little light in the sky in the earlier shots). Doesn't seem to make a lot of difference in the shot.
Here's the LED by itself on high beam:
And no, like a doof I didn't get a shot of both the yellow bulb and the LED in action... in practice, the brighter LED does sort of overwhelm the yellow incandescent. Visibility (what I can see) at night is much improved, and there's less of a yellow tinge to the scene than before. The light pattern still has a nice cutoff, so oncoming cars aren't bothered at all. And high beam also has a nice useful pattern -- same as before only more light.
I haven't yet measured current draw, but according to my onboard voltmeter, the R/R is still coping just fine.
Overall, I'm very pleased. The main issue with other LED replacements is that the emitters are in a different place than the filaments on incandescent bulbs, so you end up with a different light pattern. These bulbs seem to solve that, and at a very reasonable price, too.
The other LED bulb, by the way, is on my KLR650, which is wearing a headlight from a GS650GL. Long story... It's also working extremely well.
And yes, I did finally find some bearings and put the wheel back on my trailer...
