My headlight housings are not DOT approved, their a euro lens. So there is rule 1 broken. But, hids are designed for use in a projector housing, which is what I have.

Also, I know about the color temp to lumen ratio. The 3600k yellow are about 1800 lumens, the 6000k are 2600 lumens, the 8-10,000k are about 2300 lumens and the 12000k are I believe 2100 lumens. My budy has 30,000k pink/purple headlights and 3600k yellow fogs on his super crew. The 30,000k are like 2000 lumens. Its not a big or noticeable difference. But they all look great. If I can find better fog lights then the 20 dollar ones ill buy the kit for them.

I wouldn't call that a projector.  Maybe who ever is selling them is labelling them as a projector, but just because it has a convex lens in front of the bulb I wouldn't call it a projector.  Not a Euro lens either (if it was it would have an E-code on the lens).  Just some poorly designed aftermarket housing.  I'm sure it probably puts out a lot of light, but where is it putting the light?

I design headlamps so if I am asking a bunch of questions or saying a bunch of stuff, don't take offense, I'm just accutely aware of all the poorly designed stuff that is out there.

As to color temperature...the Photopic region (light adapted eye) is most sensitive around 555 nm wavelength which is a greenish color.  The Scotopic (dark adapted eye) is most sensitive around 500 nm wavelength which is a shift towards the blue spectrum.  There is a shift in the eye at night to using more of your cone receptors in your retina which are more responsive to blue light.  Research has also shown that bluish light at night helps to reduce eye strain and fatigue; so you feel less tired while driving at night.  We are not talking about those 'blue' halogen lights here, but rather higher color temperature bulbs that are shifted towards the blue spectrum.

After sone researching, you are quite correct. It is not a true projector. But, it does project the ligt
ht in mostly a flat line. It is not an ellipsoidal projector, like I want. The lense in the front really doesnt do much of anything, but im looking into retrofitting OEM projectors from a lexus or something into my housings! Also, I got my hids installed, and will get pictures up soon. Heres a teaser with all of my lights.

Haha. Yeah, if you look at it from a distance, its a big smiley face. I'm going to turn my KC lights into Angry Eyes by black taping the inside upper corners so they slant in a little.

Kinda like this, but not as crappy.

Okay, I couldnt get pictures of the actual installation because my friend was hounding me to put the camera down and just install them. But I will go out and take some pictures of how everything was installed in a couple of days. For now I have some comparison pictures. And a couple of random pictures of my variety of lights. now, My HID bulbs came with a metal shroud on them, it directed all of the light upwards. I removed that shroud, and I have before and after of with and without shroud. The no shroud pics look a bit bluer because they werent quite warmed up yet.


Head on with shroud

Head on no shroud

Above with shroud

Above no shroud

Head on close with shroud

Head on close no shroud



The High and low beams dont look different head on, Because They DO NOT get brighter, They move foreward and backward, which changes where the light projects. So when you hit the highs, the light just projects Up more.

I made my KC's have "Angry Eyes"

You cant tell in the pics, but you can tell in person, Angry eyes far

Angry eyes Close


Low beams on wall

High beams on wall, you can see how the light just moves UP

High beams, KC's and Fogs on wall, IDK why my driver KC is all sloppy like that


Thats All I have for now, I hope you like the Purple! I certainly do. Ill get pics of the install in a few days. I have to move my battery to show most of the wiring.

Im sure the cops will like the purple too. The light output looks horrible.

Actually, a couple of cops have told me they like them in the QuikTrip parking lot. And, the light output IS horrible. But what do you expect for 30 dollar headlight housings, that are black? I'm looking into buying a couple of True projectors off an Acura or Lexus or something to Retrofit into my housings. Once I do that it will be the shizzy.

Im not being negative. I am telling you that you will get attention from the police, even if a few of them say they like it. As for the light output, yes it does look horrible. That isnt being negative, its stating my opinion from the pictures I saw. Plus, you are the one that said "I got the black housing, because it is a projector housing and it DOES NOT rely on reflection." So it doesnt matter if you spent 30 or 300 dollars for black housings.

I'm not going to argue over something so pointless. I made a mistake buying these housing because they were falsely advertised. I was led to believe they were a True projector style housing, but the ended up being a LIE. Although thats how the internet works I guess. Everyone out scamming for money. Oh well, I can a housing that Isnt sealed beam and I also have a great candidate to retrofit with. So far I havent negative attention from cops, Even when giving them a reason to pull me over. I think they would have more of an issue with the dark blue HIDs considering it is Illegal to have Blue or Red on the front of a pedestrian vehicle. heck, I've seen green around my neighborhood several times and they dont seem to be having any cop troubles. My friend who works a QuikTrip and talks to cops all day at work said that the cops told him they have more important things to deal with than write a ticket because of headlights.

@1979 I think its cool it's different from factory, and cops will just use little things like that to pull you over when they think their is something going on, and even if your lights were factory if they wanted to pull you, they would just say something else.

If you're going for maximum light output I strongly recommend running your lights through relays if you haven't already. I was amazed at the difference it made on my 82.

Yeah, im happy with them. I like having a uniqu truck. Thats why I have kcs on the ladder rack and also why I romp it in the desert and race it on the street. And grim, the hid kit I ordered has a relay wored into it. Ill show it when I take pictures of the install.
