Re: HID vs Halogen bulbs- which puts off more heat?
Let me make a distinction here... some people get confused:
HID - High Intensity Discharge. This is a special bulb connected to special ballast/ingnitor, housed in specifically designed housing that properly aims the light put off by the bulb. These setups generally run ~200/light source and come OEM on many vehicles.
HID bulbs - A bullshit marketing term. These "HID bulbs" offer no advantages over stock bulbs. However, many people rave about their benefits because they give off light of a different color. So they look like real HIDs, and they fool the eye into thinking that they are brighter.
One more note. Summer of 2003 is the last time that HID 'kits' could be sold legally by businesses. They are no longer legal to sell. (Too many people complained about crappy installations that do nothing but blind other drivers.) So if you see some business on the net selling 'kits', they are doing it illegally and they can earn themselves some very stiff fines.
That said, OEM HID equipment is OK to resell and install. That means takeoffs that include the bulb, ballasts, and - very important - the projector housing, are still OK to put on your bike, and - best of all - they deliver the highest quality light output.
