This is very BAD advise!!! First off 10,000k is for ricers and actually doesn't produce as many lumens as lower temps (which is what we're going for here anyways). As a general rule of thumb for every 1000k in temp, lumens decrease about 10% and at 12000k the HID will actually be dimmer than your halogens. The blue/purple color will actually fatigue your eyes over a prolonged period of time. You should look for something around 4100-4500k for maximum light output as well as white color. The two major companies that supply OEM HID don't even manufacture colors over 6000k or so. To reach these extreme temperatures these aftermarket companies tend to tint the actual bulb. Second, as exSRAaron attested, putting the HID into a stock reflector scatters so much light that: 1. The output of light isn't used as effectively as in a projector 2. The high scatter of light will blind oncoming traffic as well as other riders in your group. (mirrors ya know) So angling the reflector up makes the scatter even worse, pretty much aiming the light into others eyes. Take your time and do some research, there is a ton of it available out there on the interwebs BTW that is my bike in the thread I posted above. shittygsxr on the board knows his shit about HIDs also and is a good resource for info
