Okay, did the search and I'm stillconfused!! I know the H13's are the headlight, and the H10's are the fog lights. My confusion lies in the difference between the ST & XV. Logic would dictatethe more expensive bulb (ST in this case), would be the brighter of the two, but the XV would lead one to believe itto be the brighter of the two.

Clarification please

 

H13ST Silverstar High Performance Lighting: The Whiter and Brighter Halogen
H13XV XtraVision Halogen Upgrade: Up to 20% Brighter

H11 is for foglights a.k.a. 9140, or at least I think they are H11? been a while since I got em.

edit: OK looks like H10's for the fog light, sorry for any confusion. I do think the H11 is correct, but the H10 works and is easier to find.

 

Thanks for the information, but I still remain confused. Guessthis would be a good place toinject that I am a Workers' Comp & Employment Compliance guy, and on occasion, need a bit moreclarification before I get it!!

Are you sayingXV is 20% brighter than ST, orOME lights??

 

This information is straight from Sylvania;

H13XV- same color of light as original equipment part H13 (color
temperature=3200 Kelvin)
Approximately 20% more useable light than original equipment
part H13
Average life span=2 years

H13ST- whiter light than original equipment part H13 (color
temperature=4000 Kelvin)
Approximately 25% more useable light than original equipment
part H13
Average life span=1 year

Part H13 is not yet available in the SilverStar Ultra product line but
is due to be released later this year (probably late summer / early
fall), but here is the information on what will be part number H13SU.

H13SU-whiter light than original equipment part H13 (color
temperature=4100 Kelvin)
Approximately 30% more useable light than original equipment
part H13
Average life span=14-16 months

Sylvania has no plans to develop the H13ULTRA at this time
This was to be their brightest and whitest bulb

Personally, I went the Starr HID way

 

Thanks for the info!!

 

Go with the streetglow




-Lifetime warranty
-Cheaper than SilverStar
-Side by Side with HID's can't tell a difference
-Dealing with another forum member
Import's Ebay store


Not knocking the Silverstars. I've had them in the past and VERY nice lights. But all of the above was enough to convince me to buy the way that I did. Just FYI

 

Could you tell me more about the Streetglows. Checked out a few auto parts stores and can not find them.

 

This is the only experience that I have with them so far. But I figured that with a lifetime warranty I couldn't do too bad with it. I'm very happy with the way that they perform. MUCH better then OEM's. I personally like to do business with people here on the forums if I can over some company that I have no link to. At least somebody I know benefits from it.

And they were just plug and play, just like the Silverstars.
I don't know how much you can tell from this but here is a pic after I installed them. I have the headlights and the foglights.



Just go to this link and you can find them:

thanks Rich...they look nice on your truck...I may have to steal a few of your pics for my auctions..

The headlights are h13 and the fogs are h10. They are on backorder due to NAPA screwing up everything but they should be coming soon. Or I'm gonna hve people knocking on my door

 

A friend asked a VERY knowledgable lighting guy (Daniel Stern) some questions about bulbs for his Subaru. Here is the response.
(Some good info about bulb output, life-span and cost).

Your low beams take an H1 bulb.

For reference, here's manufacturer data, from internal engineering
databases, for output and lifespan at 13.2v for standard-wattage H1 bulbs.
The numbers here are a composite of values applicable to the products of
the big three makers (Osram-Sylvania, Philips-Narva, Tungsram-GE). Each
manufacturer's product in each category is slightly different but not
significantly so. I picked H1-type bulbs for this comparison, and while
the absolute numbers differ with different bulb types, the relative
comparison patterns hold good for whatever bulb type you consider.
Lifespan is given as Tc, the hour figure at which 63.2 percent of the
bulbs have failed.

H1 (regular normal):
1550 lumens, 650 hours

Long Life (or "HalogenPlus+")
1460 lumens, 1200 hours

Plus-30 High Efficacy (Osram Super, Sylvania Xtravision, Narva Rangepower,
Candlepower Bright Light, Tungsram High Output, Philips Premium):
1700 lumens, 350 hours

Plus-50 Ultra High Efficacy (Philips VisionPlus, Osram Silverstar, Narva
Rangepower+50, Tungsram Megalicht, but not Sylvania Silverstar):
1750 lumens, 350 hours

Plus-80/90 Mega High Efficacy (Philips Xtreme Power, Osram Night Breaker):
1780 lumens, 340 hours

Blue coated 'extra white' (Osram CoolBlue, Narva Rangepower Blue, Philips
BlueVision or CrystalVision, Tungsram Super Blue or EuroBlue, Sylvania
Silverstar or Silverstar Ultra, which is just a rebrand of the
Silverstar product, also PIAA, Hoen, Nokya, Polarg, etc):
1380 lumens, 250 hours

Very interesting*

Now, looking over these results, which one would you rather:

(a) Buy and drive with?
(b) Sell?

The answer to (a) depends on how well you want to see versus how often to
change the bulb. If you want the best possible seeing, you pick the
Plus-50 or Plus-90. If you don't care as long as it works and you don't
want to hassle with it, you pick the long life.

The answer to (b) is determined by how rich your company's shareholders
want you to be, and is obvious: You want to sell the bulb with the
shortest lifespan, highest promotability and highest price. That'd be the
blue unit, e.g. Sylvania Silverstar.

Your high beams can also be significantly upgraded if you will Replace the
existing 9005 bulbs with 9011. The new bulbs are not some tinted or
overwattage version of 9005, but rather employ a relatively new technology
called HIR, Halogen Infrared Reflection. The mechanical dimensions of the
bulb are all virtually identical to the 9005, but the bulb glass is
spherical instead of tubular, with the sphere centered around the
filament. There is a "Durable IR Reflective" coating on the spherical
glass. Infrared = heat, so the coating causes heat to be reflected back to
the filament at the center of the sphere. This causes the filament to
become much hotter (producing more light) than it can by passing
electricity through it, *without* the shorter life or greater heat
production that comes with overwattage bulbs (to say nothing of
overwattage bulbs' incompatibility with stock wiring.)

Here's the comparis
