If its done correctly its a better light, but I do admit many a yahoo just shoves a 55 watt HID 4300K capsule in a Ford flat fresnel lens headlight and of course you get a massive light scatter and glare.
My vehicles use either parabolic projectors or clear cut housings with internal hood shields over the capsules.
But why would anyone care to become educated about lights?
I mean after over a decade of installing HID kits in quite a few vehicles and in most of my 12 motorcycle collection and being the owner of a custom LED flashlight manufacturing business plus a decent other business of restorations of Classic Honda Goldwings why would I want to drive or ride anything that will blind people and run them off the road?
HID is good but there is a transition period and some cars or trucks just do not adapt well to these lights.
And my ancestors no doubt were often harassed by people still on horses when they were on 4 wheels.
Transition period for who? The driver with the lights or the driver who is blinded by the lights?
These bright lights I am talking about have been around for several years and I have not become accustomed to them. they still blind me.
I am going to be the one who hits and kills someone.
