What is the difference between projector head lights and HID? and which is the better bang for the buck?

 

And can i put the 2 together?

 

projector headlights just use a different style of producing light ooutput.. stock use reflectors, projectors just send the light beam out onto the road.. and yes, you can use hid's in projectors altho the light will be scattered unless you retrofit to create a cutoff point for the light.

 

Projectors have a round glass lens at the front instead of the window of regular lights (The whole lens assembly may then be behind a window, but it is the lens that controls the light distribution). Whichever kind you use, you want the light housings to be matched to the type of bulb. Trying to retrofit HIDs into a housing or projector designed for halogens causes a wide light distribution that can blind other drivers.

 

Right. Typical headlights are just different flavors of halogen. HIDs, or High Intensity Discharge bulbs, utilize a different noble gas to get a higher light output and a difference in color.

Some people do mix them. HIDs usually can only do one brightness unless you get a bi-xenon type HID which can sorta simulate high and low beams. Otherwise, people use a traditional halogen for the high beam and the HID for the low beam.
