HID FAQ
 
Since there are so many HID questions (and requests for me to do one), I've decided to do a little FAQ. 8)


Q: What is HID lighting?
A: High Intesity Discharge lighting. HID lighting technology replaces the filament of the light bulb with a capsule of xenon gas. The light is emitted from an arc discharge between two closely spaced electrodes hermetically sealed inside a small quartz glass tubular envelope capsule. To operate, they require ballasts, which supply proper voltage and control current. The amount of light produced is greater than a standard halogen bulb, while consuming less power, and more closely approximating the color temperature of natural daylight.

Q: Do I need HIDs?
A: Many owners would argue no. The projector setup is supplies more than adequate lighting for all points and purposes. HID lighting does have it's advantages however. HID lights generally emit a greater amount of light per wattage and produce a purer, whiter light, closer to that of the sun. Halogens are yellowish in comparison. The bulbs also last longer than standard halogen bulbs and in some cases 3 to 5 times as long! Do remember that this comes at a cost as HID bulbs generally cost much more than standard halogen bulbs.

A low cost alternative many owners have tried (with success) is swtiching to Osram Silverstar H7 bulbs. Do not confuse these with the Sylvania Silverstars found in local autostores, as these do not have a blue tint to them. Blue tint, while emitting a whiter light, decreases total light output and usable parts of the usable light spectrum during incliment weather. The bulbs desired are as pictured and can be purchased through retailers such as http://www.powerbulbs.co.uk , www.suvlights.com , and many other reputable online vendors, as they are not available in the US.

Q: What HID kits fit the Legacy?
A: A H7 kit is required. Make sure this kit includes D2S bulbs.

Q: What is the difference between D2S and D2R bulbs?
A: D2S bulbs are make for projector type housings while D2R bulbs are made for reflector housings. The Legacy utilizes a projector layout, so D2S bulbs are required for correct light output.

Q: What kelvin (K) temperature rating bulbs should I get?
A: Bulb temperatures range from 4100K - 6,000k+. Higher the temperature ratings indicate more blue/purple light output. Note that the 4100K bulbs are the whitest lights available and therefore produce the most usable light. 5000K bulbs produce a bluer tint, and 6000K+ produces a more blue/purple light output.

Examples:

Note: 4300K is very similar.

5000K: http://www.xenonfactory.com/products/hid/hid_5000k.jpg

I can't think of any other questions, but I'm sure some will come up. Regardless, this is great. Someone sticky this!!!

Well, we'll have to rely on good ol' fashion bumping until it gets sticky. I like the additions btw.

Stickied. :P Thank you DM for this informative post.

You forgot one...

Q: Do HID lights blind oncoming drivers.
A: Absolutely. The intensity of the light combined with the frequency is especially blinding to drivers with blue eyes. You may see better but you're effectively turning the other driver into a Stevie Wonder without the musical talent.

I have a few ?'s
 
1. Is it true that lower color temperatures have more lumens?

2. If yes, then is it also true with more lumens you can see better (farther, wider and brighter)?

3. On the 2005 Legact 2.5 GT Ltd. the low beam is H7, the high beam is 9005 and the fog is H3...Is there a company that sells a nice plug-n-play conversion kit @ 4,000k range?

4. What would one expect the pricing to be for each kit?

5. Is it true that higher lumen bulbs have lower bulblife or higher color temperature bulb have lower bulblife?


Thanks,


CRAZY KEN

Oh, Lord...I don't know what to say except nice work, Drift Monkey.

Note that the only HID lights that effectively "blind" other drivers are when you put HIDs in a reflector housing, which is designed to scatter light thanks to the reflector. In a properly-designed projector housing that is also properly adjusted, HIDs will be fine, though senior drivers will still find the light bothersome. This, however, is because it exists in a spectrum in which older eyes are particularly sensitive. My wife is also really bothered by HIDs, which is why she hates driving at night.

Yes, lower color temperatures produce more usable light, even if they don't look as cool.

Someone on the board used a McCulloch kit that isn't quite plug and play, and kits are probably in the $300 range at this point.

One problem with aftermarket HID kits is that for whatever reason, they seem to have a lower bulb life than OE HID kits, which often last the life of the car. Generally HIDs emit less actual heat than halogen bulbs, so in theory, they should last a long time. This is often not the case, however. Ask lots of questions, particularly over at a place such as NASIOC, where lots of people have done all sorts of HID conversions.

The McCulloch kit that I ordered is the same as Weasels, which he said was quite plug and play.

Deer Killer 09-28-2004 02:39 PM

The only problem is xenons in stock housings won't auto-level.

The way that the Legacy's headlights are set up, I don't see how it's plug and play, unless there is a different routing for the wiring. With the Prodrive headlight setup (also H7), you had to cut a hole in the weather boot for the wiring. Perhaps the Legacy's is different, and it is indeed plug and play.

1. FAQ answered this, yes.
2. Yes as confimed by the answer to question one.
3. www.xenonfactory.com is a good source for phillips ballast/bulbs.
4. About $450 shipped last I checked.
5. I'm not sure about this one although bulbs with too high of a wattage rating for the light harness could melt the harness so stick with the specified wattage. 8)

Most important question....:?:

- Will the next model year Legacy comes with HIDs?
.....stay tuned. :o

Well, I installed the McCulloch kit tonight. It really was plug and play, took an hour and we were taking our time! Took the intake box out, and the battery, that gave us a lot more room for our hands. It works GREAT! Just remember to turn off your DRLs ;)
