Default Question about HIDS?

I just bought my wrx and it has a set of JDM STI non-HID headlights. I would like to upgrade them to HID and I was just wondering what options I had. Is there a conversion kit?

Any help is appreciated. I was looking to ge somewhere between 8,000 and 12,000 kelvin lights...

Thanks for any help fellas....

In short, yes there is conversion kits for everything.

In longer terms... There is but you pay the price.
JDM headlights are for RHD (not LHD where we live). The light is already in the wrong pattern (into the oncoming traffic as oppose to the sidewalk). Now you are throwing more light into oncoming drivers' eyes - not a smart move. Besides, the reason why they are non-HID headlights because they are only designed for non-HID (ie. halogen bulbs). The characteristics of HID differs from halogen. Therefore, it requires a different design of the projector (or reflector) to output the light correctly. Blindly throwing HID kits into the headlight assembly will only give out mediocre performance at best. Also, at 12000K temperature lights, I doubt you get any noticeable lighting difference other than the color of the beam.

Any kits you might recommend? Any way to change the pattern, or is it quite a pain?

Thanks again for the feedback...

We do have an HID FAQ here, right up top-
http://forums.nasioc.com/forums/showthread.php?t=664361
But, Spore is right on target here. Your JDM lights already have the wrong beam pattern for the US, and installing HIDs in them will make the situation much worse. You should avoid buying any "kit" and sticking it in the existing projectors.
It is possible to open up the lights and modify the internal plate in the projectors to eliminate the part of the beam that rises to the left. This is better than doing nothing and will take care of the problem of blinding oncoming drivers, however the lighting may still be sub-optimal. Ultimately the best results are achieved by replacing the projector units entirely with ones sourced from vehicles that had factory HID projectors, and using OEM-grade HID bulbs and ballasts.
There are a number of threads here discussing this topic that you can search for. Also you can PM Lightwerkz for information on their retrofit services.

drive up to a wall and look at the beam pattern first.. the passenger side should be higher than the driverside

if you want an upgrade, upgrade the ballasts, harness and bulbs<if they need replacing>.. otherwise, why bother.. if you're going to say that 12k is brighter than 5k, that's not the case and you probably shouldn't be playing with hids

you need to do some reading up on the kelvin (k) rating for HID lamps.

4300k is the best bulb for nighttime use. it provides the most usable light. this is what most cars come with from the factory.

5000k is the most i would go. after that the color looks nice, but you start to lose the usable light.

8-12000k is too much color. 12000k is practically purple ight. it sucks, and it is the most annoying thing i have seen on the road.

my suggestion is 4300k, or if you want a bit more color, go for 5000k.

+1 for contacting lightwerkz. you will need to retrofit a usdm LHD HID projector in there. most people use acura tsx projectors. otherwise ****ty HID kit + RHD subaru projector= horrible light in front of you, and a bunch of highbeam flashes from other drivers.

I have researched this topic several times and I always seem to get two different opinons of what is good quality hids with the lighting look I like. Does 6,000 Kelvin give a good blue hid lighting. A good blue and just better lighting at night is what I am trying to achieve.

Thanks again for the reply's guys. I did read the HID faq thread, but I did not seem much specifically related to my light set up.

There is no such thing as "good blue" lighting. As you go higher up in the color temperature scale, the light contains more blue content which equates to less visible light on the road and more glare. Here is some good reading on the subject, it applies to blue HIDs as well as halogens-
http://www.danielsternlighting.com/t...blue/blue.html
People often put high color temp HID bulbs in their lights in a misguided attempt to duplicate the look of factory HIDs in certain European vehicles. In fact those lights are 4300K and are actually white, the "blue" look is caused by chromatic distortion at the edge of the projector beam when viewing them from the side.
What we are telling you here, is that for the lights you have in their existing form, you cannot have "good quality HIDs". You have to modify the lights, preferably by doing a full retrofit with LHD HID projector units.

Is that process very difficult and I am assuming expensive? Anybody recommend any shops that may be experts with this kind of conversion in Seattle? I know of world one performance, but not many others...

Thanks again for the help guys... I really appreciate it..

Already mentioned this, but send a PM to Lightwerkz. They are a NASIOC vendor and can perform this service for you. They're in NJ so you'd have to send the lights to them.
