So in the US, the Philips Xtravisions (I'll call XT's) are brighter than the Sylvania Silverstars (I'll call SS's)? I have a pair of SS 9004's isntalled in one car, and bought a pair of SS H3 fog lights bulbs but haven't installed them yet. If the XT's are brighter, I can return the SS H3's I just bought. I also need another set of 9004's and H3's for another car.
As far as cost, when I bought one pair of SS's (9004) back this fall, they were $20e - one $10MIR if you bought two = $15e. When I bought the other pair of SS's (H3) a couple weeks ago, Advance Auto parts had all SS's buy 1 get 1 half off, so they also ended up $15e.
This week, in the Pep Boys flyer, they are advertising SS's for $16.88 a pair - $5 MIR = $11.88/pair = $5.94e = obviously a mistake.
Also, some high output bulbs have been known to burn lenses and wiring/connectors. I have heard zero reports of the SS's doing this. What about the XT's?
But the SS's do seem to have a short life. What abou the XT's? Would the wiring harness upgrade TechnoKid mentioned fix this?

European silverstars are not the same as the us counterparts. European silverstars are comparible to the philips Vision plus (+50%) bulbs.
Here's a quick run through: Any bulb with a coating will not be as bright as the same bulb without the coating. The coating reduces the amount of light (lumens) as it is another thing besides the glass (or quartz) that it has to pass through. The US silverstars are basically coated euro silverstars.
As far as I know, the silverstars and the XT bulbs are the same wattage as a regular bulb, they just use a different gas mixture, pressure and a more exact filament alignment and winding. The only exception to this is the long life bulbs, which have a slightly reduced wattage (and thus reduced output) to increase bulb life. The higher output bulbs that you speak of could possibly be overwattage bulbs, which definately have a shorter life compared to regular bulbs. Also, running rally bulbs or overwattage bulbs on stock wiring is a recipe for disaster. The higher wattage can melt, destroy and create a fire hazard in the stock wiring. This is why you need a harness; they are made (or can be made yourself) with thicker wiring, an a seperate relay to draw current directly from the battery.
Getting a harness is a good idea for any vehicle (with halogens that is), because more often than not, your stock bulb sockets aren't getting a full 14V (13.8 really), and thus your bulbs aren't as bright as they could be (w/o significantly reducing the life of the bulb because of too much voltage). Also, a harness helps prevent fluctuations of voltage that may be inherent in the stock wiring. Voltage fluctuations can significantly reduce the life of a bulb, which is why its also a good idea to turn off the lights before turing off the engine, and turn on the lights when the engine is started, not before (turing on the headlights before the car is started draws amps and reduces the ability of the car to start easily; it strains the electrical system and starter).
In H3, and for all practical purposes of fogs, I'd definately get either clear H3 bulbs, or yellow or gold tinted bulbs. The bluish hue of the SS would do not good in fog or in inclement weather as the fog and wet road would do nothing but absorb the wavelength of the color of the SS bulbs. A yellow or clear bulb would create better contrast. Think of it this way: sunglasses and a sky blue sky. You look at the sky w/o sunglasses, with amber or yellow sunglasses, and with blue sunglasses. The amber and or yellow glasses are going to create better contrast then the blue ones. For yellow H3 bulbs, try this place:

Since you originally said "Silverstars in europe are better than the xtravision.", I assumed you were saying the XT's were better than the SS's, in the US.
The only reason I stated that the XT are better than the SS in the US is because the XT don't have a coating on them. As Far as I know, there is not a european "+50%" bulb out there. The best you can get in a 9004 is the XT bulbs.
Yes, the SS's are the same wattage as OEM. I wasn't trying to say they were one of the higher than OEM wattage bulbs I mentioned, that could melt things. Sorry that wasn't clear. But since the various mentioned above are normal wattage, why do they not last as long?
Do you know what brands/models are the high wattage bulbs, that shouldn't be used with stock wiring? Even w/ upgraded wiring, they could still melt the lenses.
I'm not exactly sure as to why they don't last as long even though they are the same wattage. I believe it may have to do with the gas mixture in the bulb and the pressure at which the gas is. Any bulb that isn't rated at stock wattage shouldn't be used with stock wiring. Yes, higher wattage bulbs can still melt the lenses even though a harness was used; the bulb puts out much more heat, and most plastic headlights can't take it, although if the fixture is glass, it may be safe, but only if the reflector is metal, not plastic.
So you're saying an upgraded harness could give the stock wattage bulbs a brighter output? How much would this reduce bulb life? I imagine the mfg rates theirs at 13.8.
The bulb life thats spec'd on the package is rated by the manufacturer at 13.8 volts. Running a hraness should yield a bulb life close to what the manufacturer spec'd becasue thats the voltage the manufacturer used to test it. It would reduce the life compared to running it on the stock harness, however.
I see what you mean about the bluish fog lights, but the SS's are very lightly blue tinted. I wanted a super white bulb, which is why I bought the SS's, since they're close to white. And I couldnt find out about any super white bulbs that aren't very blue or that wouldn't possibly melt the lenses. I bought the SS H3's to match the headlights, but maybe it wasn't a great idea. I definately don't want yellow though. I rarely actually drive in fog. I'll either keep the factory bulbs or may have to use the SS's I already bought.
If you are gong for cosmetic reasons, then the SS would be a fine choice, and a street legal choice( actually, barely a street legal choice, the SS (us) bulbs are close to being considered a "blue" bulb). But they do cost more than regular clear bulbs.
Also, the page you linked says:
"SUPER WHITE bulbs have blue coloring to produce a white/blue light. They give the look of HID light systems. Premium versions have +30% more light using the same wattage. "
What are the premium versions?
Premium versions are bulbs that contain a mixture of xenon gas and/or krypton. The super white bulbs are sometimes just +30% bulbs with a blue coating, and would be brighter w/o the coating. Sometimes the super white bulbs are not coated +30% bulbs, but coated high-wattage bulbs. And, super white bulbs do exactly that, they only mimic the look of HID, and could not ever perform to the level of HID. A clear +30% bulb will usually always be brighter than a "super white" or "blue-bulb" unless the blue bulb is an over wattage bulb.
About HID:
I don't see why they cost so much. Does seem like there's enough in the kit that would cost what they do.
The only xenon bulbs are HID bulbs, correct? So all the halogen bulbs that are labeled xenon are incorrectly labeled. HID are AKA gas discharge?
I was reading a post where someone installed the HID kit from Autolamps Online and was pleased. They dont have a 9004 kit though. Their page says the Philips HID xenon bulbs are designed to last the lifetime of the car!? Though they can go out, and would cost $100 or so a piece to replace.
HID has 2-3 times the output, so do they run any hotter (melt lense)?
HID cost more than halogen because of manufacturing process. There are not many quality manufacturers out there; the ones that I'm familiar with are Osram, Philips, Koito, basically OEM manufacturers, although Osram and Philips make a majority of the components such as the bulbs and ballasts. Xenon bulbs are HID, yes, but xenon halogen bulbs are also xenon, just not a gas discharge xenon. Gas discharge uses onle gas to create a light "arc" where as halogens uses a filament to create the light source. The lights do put out 2-3 times more than halogens (more lumens, not more heat), but they don't run any hotter than halogens, in fact they run cooler, using only 35 watts.

So people (and me) paid more for the SS's that aren't as bright as XT's, just for a white look? The XT's have the normal halogen yellowish look, correct? And the XT's would have a fairly short life too? Are these similar to the Philips HV? Are these all "+30% bulbs"? If so, which are +50%? The higher wattage bulbs maybe? The 30% and 50% thing is a little confusing to me without knowing what brands/models/types these are.
You said there is no 50% Euro bulb, but you also said the Philips Vision Plus is a 50% Euro.(?)
There isn't a Euro crossover # that is a 9004 is there?
BTW, I made a type above, saying XT's were Philips (fixed).

I've read this several times, and it still doesn't make sense to me. You seem to contradict yourself. ?
If you are gong for cosmetic reasons, then the SS would be a fine choice, and a street legal choice( actually, barely a street legal choice, the SS (us) bulbs are close to being considered a "blue" bulb). But they do cost more than regular clear bulbs.
So I guess without going to HID or using higher wattage bulbs, my choices (not knowing what a 50% bulb is) are a 30% super white (bluish) bulb to look similar to HID, like the SS's, or a 30% clear bulb that is brighter but traditional halogen yellow light, like the XT's (and...?). And it seems the SS's are the best 9004 super white OEM wattage bulbs I can get.
I suggest that if you really want to get into a HID retro, don't get a kit; the optics between halogen design and HID design are VERY different. The best way would be to do a swap of parts from an oem donor, the most popular today being projecotrs. Automotive lighting FAQ Read through the faq there and youll gain a lot of info.
I doubt I could get HID changeover lenses for my vehicles.
My lenses are basic square flat ones so I don't think I'd get much of the prism effect, as in the first pic MercenaryForHire linked to. I've seen several HID kits installed and the patterns all looked good. But perhaps the kits will be outlawed soon anyway.
BTW, I have a '00 Nissan Frontier, and a '87 300ZX.
