Default Headlight test results (visual evaluations only, kids)

The contenders:

Eurolite 85/100
Sylvania SilverStar
Sylvania XtraVision
stock Sylvania
Philips Hi-Visibility

The Eurolites were a blue joke. They were even worse than the stock Sylvania bulbs, and high-beam performance was hilarity. I don't know how this company stays in business, frankly.

The SilverStar changed the color temperature, but you didn't really get much more light than stock. That is, you got a bluish-white light instead of the yellowish light of stock, which is easier to use if you want to see, but as regards illumination, the difference is negligible.

The XtraVisions were better than the SilverStars, but hardly any different from stock. There is a change in the beam shape/spread, however. These are good replacements for when the stock lights go out, because they're readily available, but don't expect to see any dramatic improvements.

The Hi-Visibility bulbs owned. They are frighteningly close to my Prodrives, with the VisionPlus bulbs installed, at least 95% of the light. Now, because of the 9007 reflector design, the Prodrives are a better working tool because of how the projectors focus the light.

Both light setups (stock and Prodrive) throw a blanket of white light, bereft of any bluing, in front of the car. But the Prodrive lights throw light farther than the stock lights with the Hi-Vis bulbs (they're projectors...duh!).

Interesting tidbits:

The Hi-Vis bulb is fatter and longer than any of the other 9007 bulbs in the test, which are all the same size. Also, the build quality of the Philips bulb is superlative. This bulb just owns in every way.

Now, I didn't have any sort of light measuring devices, other than my eyes (and those of my night vision-impaired wife, the real reason I seek better lights and went with the Prodrives), and the pitch-black streets of Highland Park. The real test for me was which light enables you to SEE better. The winner was clear.

Note that the Narva bulbs that Peaty has are made by Philips. I would suspect that were you to find a 9007 Narva, it would offer the same performance as the Philips.

This test is by no means complete. There are a host of "tuner" bulbs out there from companies like APC, and other "overwatt" companies that I didn't bother with. Those things are all suspect, IMHO. I wanted to get some Hellas in 9007 for the test, but was just too lazy. I'll probably lay some in and if I ever get ambitious again, fool around with them.

Oh, light bulbs are a lot easier to fool with than suspensions!

How much are the Hi-vis bulbs?

The light was bright white?

Bright white, with slight yellowish tinge that is barely perceptible. They were about $35 shipped.

No, but you could see better with 'em, which was my barometer. There was blue tint in the SilverStars, and none with the Philips. To clarify, I wasn't weighing any aspect of how the lights looked, simply when you are driving, can you see better or worse, or about the same compared to stock and further, to the control lights, the Prodrives.

I got mine here:

Hey, it was a whole 22 degrees on Saturday. Compared to 8, it felt almost tropical.

Default Stock and loving the look...

I'll probably mount some driving lights behind the grille, or in the fog slots, and sell the Prodrives, which are posted in Private Classifieds.

I've heard good things about Hella 500s, but they might be too much light...

you want to know how I got these? There is a slight trick move you have to know about installing HIDs for a negative-switch electrical system. Grounding is very important.






I got the MAD CATZ HID kit.. best HID kit around! www.liteswap.com

Tonight I put some Philips Hi-Visibility 9007 HV in my wagon, replacing the Silverstars I have had in for about 6 weeks. And thanks to you folks who have done some comparisons that helped me.

Here are my first impressions.

I first replaced the driver side and went for a short drive on some dark streets. The Hi-Visibility light seemed to shine farther and certainly wider, to the left side of the road.

I came back and installed the other and went for a long drive on some dark curvey roads. The improvement seems to be pretty dramatic. I know my 'lighting memory' is not that long, but they seem to shine farther and wider. The darkness in front just lights up. The sides of the road light up and that light seems to extend farther than the Silverstars.

I like the 'color' of the Hi-Visibility better. I was impressed with the Silverstar's brightness or 'color', but I think some of that was the way the whiter light shone on signs and stuff. The Hi-Visibility light the sign up, but don't make the white speed limit signs as white as the Silverstars.

I just came back from another dark drive on a road that I have spent many miles and the road is definitely lite up more; not only in front, but I had the feeling that I could see the sides much better and might even be able to spot a deer (if one were standing on the side, thinking about doing a double-dare with my car) much easier. The result was I felt safer cause I could see more.

Hmm, how does Philips do it? The bulb is longer than the Silverstar; the back of the box says "Have filaments in a unique postion (sp) to optimize light on the road. The Result: Superior output". Maybe that is it, anyone else know?

Nice to see that I'm not crazy. Those things rock. I believe that the SilverStars have a higher Kelvin rating than the Hi-Vis bulbs, which explains their different color. But the Hi-Vis definitely own.

If I weren't so used to my Prodrive projectors, I could live quite happily with the stock/Hi-Vis combo, for sure.

Default hmmm

i am running a pair of philips high visiblity bulbs. I remember I bought them from Ames when they were going out of buiness... they had some crazy sale for going out of business and I think the pair cost me like 12 or 15 bucks.

I dont know if they are the same one, I think i still have the box at home, because I am keeping my stock lights in there. I just remember that the box said 30% brighter than stock.... I actually bought them hoping they would be a tad bluer, and not expecting any more light...so I have no idea if they are brighter or not....

I will check my box and see if they are the same ones you guys are talking about-- that would be a great coincidence...

what does your guys packaging say?

Kevin,

Any suggestions for replacement OEM foglight bulbs? One of miine blew a few weeks ago (prob cuz I did the foglight mod and drove with them on 24/7). I know that they are H3. Mine had a blueish tint to them (have yet to tear the assembly apart to take the bulb out-original owner put them in!)

ANy suggestions? i've heard that yellow lights help you see more. Any truth to this? I might consider yellowstars (???) for the fogs. . .

that's what i want to do with mine, i want the yellow, like the lexus's(or Lexei ) have. i don't know, however if the yellow ion, or yellowstars will be that yellow, i may have to tint the lense.

on a side note, if anyone wants vinyl decals cut or enough people want yellow tinting on their fogs, i can get high temp yellow tint for the headlights and cut them on the plotter, dirt cheap.

Dunno, I hardly ever use my fogs. I did once when we actually had fog, and they worked pretty well and seem awfully bright. I'd leave 'em be, unless you live in a foggy area.

Philips WeatherVision/ AllWeather and Hella YellowStar has a yellowish light with the premise that it improves visibility in bad weather conditions. I know my hella optilux fogs seem to cut through fog/rain better than the OEM fogs.

Default You want light? I gots your light right here, jerky ;)

Bulb upgrades pale in comparision to a set of Hella 4k's. Stupid amounts of light. I've saved many an animal with those, including a couple deer (more like saved ME in regards to hitting deer). The look is not for everyone though.

Shame they don't make the Hi-Vis bulbs in H7. That's what my twin beams take.

Jaysus, Bob O! People must think they've died when they see you coming toward them...move away from the light...

Oh, in H7, you can use the Philips VisionPlus bulbs, which are even better than the Hi-Visibility bulbs. I run VPs in my H7 Prodrives. Get them at www.powerbulbs.com. They're about $40 (shipped) per pair, and worth every penny.

Thumbs up wayyy helpful review

Kevin - it is so awesome that there are guys like you willing to do this stuff. I mean, this is a thousand times more useful ( and especially trustworthy) than reading a vender ad that says "this is the best replacement bulb". What I like to do is bookmark the link that's given to the site on where to get this stuff so I know where to go when I need it, because it is more my nature to wait till one burns out and then replace them.
I know this is probably seen as corny but unless someone says something to assure you your efforts are much appreciated I'm afraid you might stop doing this kinda thing, and I just can't let that happen!!

My testing results are similar to gtguy's too. Just to throw in my two cents

I think if you want to just go to the local store and get some bulbs get the Sylvania XtraVisions. They don't look as white as the Silverstars but they seem to have more usable light. There is no scientific proof that I have been able to find that shows whiter light at night is better for vision. Things like 20% and 50% more light on packages is just marketing and really dosen't mean squat as far as I'm concerned.

I've been pretty happy w/ my Osram brand Super High Efficiency Plus 50 bulbs. It sounds like they are similar to Hi Viz bulbs as mentioned.

A few things I've gleaned in my search for good lighting.

Any coating on a bulb will reduce the output. If you get bulbs,get ones that have a clear glass for headlamps.

The same goes for the lens, even more so. If you put some sort of colour in the glass or plastic on your headlamp/foglamp and it's not clear it will really reduce the output. Yellow lenses are a thing of the past, same goes for coloured films. I've seen numbers like a 20-30 % reduction in output due to a yellow lens. Think of it, light contains all colours, in order to see one specific colour you have to subtract all the other colours.

The closer to the blue end of the spectrum a bulbs output the more scattered the light will be. Blue is the main component in glare. This is why sunglass companies always tout their blue blocking abilities. Moisture in the air scatters light and if you have blue in your light it's makes matters much worse.

I've been searching the net and re-reading some of my college material on how the eye works. I wish I could find a member that was an Opthomiligst. I have some questions I'd like to bounce off them. The eye works very differently at night than the day time. Something that actually helps night vision is protecting the eyes during the day w/ some good quality sunglasses.

This is what I want to discuss w/ someone that really understands the workings of the eye. With highway driving you really don't want the road directly in front of you very bright. It will make it so your pupils get smaller and reduce the ability see as far down the road. Also, the eyes tend to be drawn to motion, if the road in front of you is lit up, you will sort of want to look there because you can see it whizzing by. Ever notice in a snow storm you can be dazzled and freaked out when you stare at the snow flakes coming at you. It's something like that. The eye has cones and rods at the back where the light hits it. Cones perceive colour and are concentrated at the center of the retina. Rods are for night vision they see B&W and motion better. This is one reason your eyes are drawn to movement especially at night. The rods being at the edges of the retina you have good peripheral vision. If you have too much light up close you make your cones come into play more than your rods reducing your night vision. Plus, if you don't notice something till it's just in front of you, you are not gonna have time to react and you will run it over if you are at highway speeds. This is why I think it's counterproductive to have your fog lamps on when it's not foggy. I think HID retrofit kits are the worst offenders of too much light directly in front of the car. The lens wasn't engineered w/ this type of bulb system in mind. The ones I've seen are very very bright in front as well as down the road. Anyway, I'm rambling and I apologize. Maybe because my hearing is so bad (I have to wear hearing aids in both ears) I go a little crazy about my vision. Just to site a good reference have a look around here:


http://hyperphysics.phy-astr.gsu.edu...n/rodcone.html

http://hyperphysics.phy-astr.gsu.edu...n/rodcone.html

One good cut and paste from that site:

----------
Rod Details

The rods are more numerous of the photoreceptors, some 120 million, and are the more sensitive than the cones. However, they are not sensitive to color. They are responsible for our dark-adapted, or scotopic, vision. The rods are incredibly efficient photoreceptors. More than one thousand times as sensitive as the cones, they can reportedly be triggered by individual photons under optimal conditions. The optimum dark-adapted vision is obtained only after a considerable period of darkness, say 30 minutes or longer, because the rod adaption process is much slower than that of the cones.

The rod sensitivity is shifted toward shorter wavelengths compared to daylight vision, accounting for the growing apparent brightness of green leaves in twilight.

While the visual acuity or visual resolution is much better with the cones, the rods are better motion sensors. Since the rods predominate in the peripheral vision, that peripheral vision is more light sensitive, enabling you to see dimmer objects in your peripheral vision. If you see a dim star in your peripheral vision, it may disappear when you look at it directly since you are then moving the image onto the cone-rich fovea region which is less light sensitive. You can detect motion better with your peripheral vision, since it is primarily rod vision.

----------------

Here is my link to some of the things I've looked at bulb wise.
