This is a great write-up on why drop in hid kits suck. Not only the glare for other drivers, but the bad light pattern that is projected/reflected onto the road.

I really hope this thread can help you guys. Ur making the road more dangerous than it already is by adding a HID kit to your car. so please do HID the right way by doing a retrofit.

HID kits are illegal do to the glare that they cause. Glare is Light that is emitted in a Uncontrollable path. When light is traveling in a uncontrollable path it can hit other vehicle operators affecting there vision because of the High amount of uncontrollable light that is being Emitted from a HID kit in a standard Halogen housing. If you have ever turned a flashlight on right in front of your face while it is dark out, that is the same feeling that the other drivers on the road experience from a standard HID kit.

OEM Vehicles such as Mercedes, BMW, Audi, Lexus are all equipped with HID or Xenon Headlights. Some use reflector housing’s without projectors. Others use HID projectors.

The Lexus IS300 is a Prime Example of a HID reflector housing. It does not use a Projector. It uses a Specially designed Reflector housing that is meant to use HID. This does not create the Super sharp cutoff. But it does control where the light is being Emitted.

Other vehicles such as the Honda S2000 Use HID projectors, These Projectors are meant to use HID. They are Specially Designed and have been tested Hundreds of times to get the right projection of light while maintaining a Good Cutoff.

To date, NHTSA has investigated 24 HID conversion kit suppliers; all investigations have resulted in recalls or termination of sales.

yea, they have ok cutoff and light spread, but nowhere near as good as a HID projector. Halogen projectors are actually designed differently than HID projectors, but they aren't as bad as most reflectors when putting drop-in kits in them.

You can see in that picture, the light spread from them is very narrow compared to HID projectors, and there is a big hotspot too.

LOL. Nice pics SilviaDriver.

If you think about it. The H4 bulb has two filaments. The are positioned going across the bulb and emit the light outward from the filament. The HID produces light through the arc in the bulb which goes from the base of the bulb to the tip. Anyone get what I'm saying. This is all just me thinking about it though. I don't really have any proof.

I still like HID's though. I wonder if any manufacturer would make a HID housing for pop-up/rectangle whatever they're called lights in the future.

That's some good information. Yeah I believe it is the arc of voltage that causes the light, so many volts are used just to start it...

I sincerely hope you copied and pasted that first paragraph... Here, I will fix it for you:
HID kits are illegal due to the glare that they cause. Glare is Light that is emitted in a uncontrollable path. When light is traveling in a uncontrollable path it can hit other vehicle operators, affecting their vision, because of the high amount of uncontrollable light that is being emitted from a HID kit in a standard Halogen housing.

2 of my pops' sisters are high school english teachers, I found myself in ONE of their classes for my senior year honors english class... My average for the year was 106, not because of nepotism, but because I was fucking SCARED of the shit I had witnessed in the previous 16 1/2 years of my life. I grew up around it, it happens.

I just got a set of 5300k hids on my s14 zenki and it works pretty well in terms of visibility. Its not messy like the pictues above. Overall, im satisified by the outcome of the hids i got and really improved the light output compared to stock. I think aiming your headlight is the key to making the light more clean.

Yea, basically the biggest problem is the brightest parts of the halogen filament are opposite the brightest parts of the HID arc, in addition to being positioned differently as you stated. The brightest part of the halogen filament is the center, and the ends are dimmer. But with HID, the ends of the arc are actually brighter than the center. So from the get go, the light is hitting the reflector in different points, and at different angles than the halogen light does. And then the reflector itself is not designed to handle that much light, so the end result is crappy, as shown above.

silviasr20det: aiming the lights correctly is not the key. You cannot change the characteristics of the headlights simply by aiming them.

I don't think it's a matter of the amount of light. It's the source. If you put higher wattage bulbs in a H4 housing the light pattern is basically the same just brighter. I think it's the positioning of the source like we stated earlier.

silviadriver: flip those shields already!

those are stock s15 projectors with Catz HID kit. ive gotten comments about how OEMish the setup looks.

all halogen projectors are created differnetly. i believe the 240 projectors are created better than integras and other cars which is why they can handle them somewhat better than other cars. but i can always be wrong

ill flip them when im not so lazy and have more time on my hands.
