We use 9004 bulbs which contain in effect 2 bulbs, but yall knew that :cool: So what have you had success with changing to HID? Names & numbers would be nice

Never had anyone in Tx or Ca. Inspection mention it.

Never had anyone in Tx or Ca. Inspection mention it. UT, CO and several other states. Heard from people in all of them. Cops will bust you here in CO and UT for sure. Neither the Gen 1 nor Gen 2 housings are built for HID. What you end up with is a headlight spraying light hither and yon into incoming traffic. Even though people THINK its an improvement. It isn't. In fact, its actually a giant step backwards. The only way to do a HID conversion is to replace the housing assembly with one specifically designed for HID and there aren't any. Seriously, blinding oncoming traffic isn't cool. Edward

Yea well it's a slippery slope. Some manufacturers do the same with little or no modification. If you dip the bulbs, install, and aim them properly it would be fine. If the manufacturers do by chance mod the halogen housing for hids they typical dip or shield the bulb. I'm guessing they use a computer program however to design and place the shield which we don't have at our disposal. All that is really needed is to dip (cover) the top and bottom of the bulb so it emits light at the same spot as it would being a halogen. Problems arise because an hid bulb is longer than the halogen so it is emiting light from areas that the housing wasn't designed for hince the light scatter. Light is light regardless of the source. The main reason they use the projector type is cause it's much easier to create that sharp cutoff line but even they glare at times. Just the nature of the sheer intensity of hids.

What year is your MS? My 01 uses 9007 bulbs. Not sure difference between the two are. I have used the siverstar ultra previously, I liked them also. Not sure if they have a good LED bulb yet to use in place of ours yet. I know I swapped my reverse lights to Cree LEDs and love them much better then stock.

Its a 97, it seems to have 3 adjusting spots also. Could not get mitsu serv site up at dealer to chk manual.

... I'm guessing they use a computer program however to design and place the shield which we don't have at our disposal. ... That is correct. That is exactly how its done. And, that is where all this falls apart. That is NOT how head lights are designed. Headlights are designed to emit light in several areas and exclude light in others. They are NOT designed to just project light in a band. THERE IS NO WAY to 'dip' or otherwise modify a bulb to emit light in the same pattern as headlights are designed to do. I have both Gen 1s and Gen 2s so I have both the original glass headlights as well as the plastic ones. The plastic ones are less defined, but the glass headlight housings are designed to project light to illuminate the passenger side shoulder, as well as upcoming street signs. Its tapered on the DS to minimize the light in the oncoming late so as not to blind oncoming traffic. And this only scratches the surface. ALL HEADLIGHT ASSEMBLIES are designed to do this (among other things)! They do it to a better or worse degree but that's how headlights and headlight housings have been designed for for decades. Headlight bulbs and housings ARE actually designed - by real engineers. Manufacturers do not just stick a bulb in a plastic box and call it good. DOT certified aftermarket housings and bulbs have to be designed to do the same thing as OEM housings. That's why there are so few of them available. Its expensive to do it right. Edward

Edward Yea mine are aimed in this manner. That term engineer is thrown around rather lightly these days. Anyone who has owned anything knows what I'm talking about. How many times have the words "who the f^#% designed this thing" come to mind. The optional hid setup on the earlier altimas (early 00 body style) is a prime example of what I was getting at. Had the same design for a couple of years before hids were an option. The shielding is nothing more than a metal ring on the bulb right below the arc while leaving the top and bottom exposed. There are quite a few others that are just the same and sometimes they just put it on the arc and leave the rest of the bulb exposed. Think most are stuck on there just so they can say they are shielded. Most of the DOT certified housings on some cars today are subpar at best for both front and rear.

Meh. I'm not all for HID's in non-HID housings, but I'm not all against them either. Some housings they look okay and don't blind other people. Some are horribly bright and do horribly blind people, usually the clear housings. I think the glass housings on my Sport would lean towards the non-blinding category because of the deflector pattern built into the glass. It's those clear housings that blind people. This is coming from someone who has installed HID's on probably 100+ cars (it's not illegal in my state). Some blind the crap out of you, others are okay.
HID's are fading though. The switch to LED is here and they don't blind as bad. Our shop stopped carrying HID's and switched to LED. Lower power consumption and a ton more reliable. Probably 60% of people we did HID's for came back with burnt out bulbs or fried ballasts still under warranty. They just aren't reliable, no matter which brand we tried.
Now if you go with the lower scale of the color temperature, they aren't anywhere near as blinding in a non-HID housing. The yellowish or pure white colors aren't as bad as the more blue colors.

Yea wasn't trying to cause a ruckus.
Yea the LEDs are the new thing and now lasers are coming into the game. Pew pew --------------

... The shielding is nothing more than a metal ring on the bulb right below the arc while leaving the top and bottom exposed. .... They do not just plunk a bulb in a housing. In most instances, those little metal 'rings' are reflectors. They do not just block light, they redirect the light to bounce it off the HOUSING reflector which then redirects the light in the desired pattern(s). Housings and reflectors are computer modeled. None of it looks like much, but there's a LOT to it. You can take two housings and put them side by side and the human eye can't tell any difference. But, the light pattern will be dramatically different. I'm not trying to be pissy, belligerent of get on anyone's case ... but this is how we end up with vehicles on the road that blind oncoming traffic while providing unsafe illumination for the driver. The vast majority of the population does not realize that a head light isn't just a bulb with some shiny tinfoil behind it. Even the way bulbs are built dictates how a reflector needs to be designed and where and how its positioned. None of you been doing any reading on the problems with putting LED bulbs in standard incandescent housings? Plenty of posts out there from pissed off LED purchasers who end up with 50% of the light they had from a standard bulb because it's all going the wrong direction and the housing isn't built to redirect it.

Edward On the d2r bulbs it is just a shield to block light from hitting the bottom of the reflector and bouncing up into oncoming traffic. Technically they reflect light back inward towards the top of the reflector but ther main purpose is to block the light. What they use in the Altima housings I mentioned and quite a few others. Some of them however just shield the arc when technically they should shield the length of the bulb on the bottom to block the light from bouncing up. If they actually designed the housing around the bulb it wouldn't need a shield. Just to throw it out there I've been flashed before with the sylvania silverstars and ultras just because the simple fact that the brighter bulbs caused the light to travel further. Had nothing to do with the reflectors. Just had to re aim. If the original bulbs were brighter you would have the same result. I totally agree with you about just sticking an hid bulb in any housing and calling it a day but at the same time when done right it isn't an impossible feat. I mean I've been blinded from stock setups at the same time so just because you get blinded from someone doesn't mean it's someone who did an improper install.
