I'm not here to turn this topic into a pissing match of-it must be better because it's harder to look into the light. I worked for years in a business that deals with the assembly and manufacturing and setting up of xenon or hid lighting. So unless you have some educated feedback with some form of research behind it, don't bother and read this first. This is what i've been trying to tell people for years who have been wasting their money on putting xenon bulbs in halogen bulb lens assemblies. Also, if you haven't driven an OE xenon equipped vehicle on a dark road with no street lights, you won't really know the difference. I've seen people spend millions on gimmick mods and this is a big one.
The most dangerous part of the attempt to "retrofit" Xenon headlamps is that sometimes you get a deceptive and illusory "improvement" in the performance of the headlamp. The performance of the headlamp is perceived to be "better" because of the much higher level of foreground lighting (on the road immediately in front of the car/motorcycle). However, the beam patterns produced by this kind of "conversion" virtually always give less distance light, and often an alarming lack of light where there's meant to be a relative maximum in light intensity. The result is the illusion that you can see better than you actually can, and that's not safe.
Here's a link that you should take the time to read before making an uneducated reply. There's way more links to DOT research on his site as well. This goes way beyond color temperature and whatever else you read on the side of a chinese parts box. I read a lot of garbage in this and a lot of other forums so I usually don't waste my time with responding but this is an important topic. If you're like a lot of posers who spend money on clear lenses and garbage that you think will make you cooler, stay in your happy place and keep doing what you do. I believe in function first.
Mods- This should be made a sticky if the site sponsors aren't offended.
