Piaa23-10101 Xtreme White Hybrid H1 Bulb (3900K - 12V 55W), 2 Pack

So there are a lot of people on here that think they will get a "White" light out of this. Unfortunately you will not but then again you dont want a White light for certain driving conditions like Rain, Snow, Dust and Fog. If you go past 6000k on color temp or even touch it the light will reflect back at you so where you will see nothing but you life flashing before your eye's!!How do I know that? Well lets just say on one vehicle I did LED drop ins and the bulbs were at 6500k temp and in snow you might as well forget it. With the new lights it has now it is more of 5700k and it has full on projectors.Now for these lights I installed them on an old 1993 Nissan Pathfinder. I still have the factory Nissan headlight housings and to say the least they do project light pretty well but the bulbs that were in ut were kind of lacking.... And also showed some sign of oil/grease on the glass.... Not a good thing....After installing the new bulbs I could tell they were brighter. I could also tell that the light pattern was filled in a bit more. Distance? Unfortunately I cant speak on that as of yet since the vehicle is not quite driveable yet(soon I say!! Soon!!!!). I am expecting to have a fair distance with these but also understand that without projector headlights it will only do so much.Installation was a winch but then again it all depends on your vehicle. You can thank engineers for that!!So are you wanting a brighter bulb withput breaking the bank and having a good life? Then I suggest the PIAA brand to you!! Even if you go Xtreme White Plus you should be just fine. Just remember that if you have auto headlights life expectancy will be lower than normal.

First off, these bulbs and the packaging exactly matched the pictures of the product being used online, so no misrepresentation there. However, where it says "up to 3900K" on the front of the packaging, and then on the back, where is shows a picture of very yellow light coming from a standard halogen bulb, and then a very white light coming from the PIAA XW Hybrid bulb, that is not what I saw coming out of my headlights with the PIAA bulbs installed, and I will explain more of this towards the end of this review. I installed the pair of PIAA bulbs on one side of my car (low beam projector and high beam reflector lenses) and on the other side I had a pair of relatively new OSRAM Night Breaker Unlimited bulbs installed in both the low and high beam lenses. When you looked at the front of the car with the headlights on, you couldn't tell a color difference between the PIAA bulbs and the OSRAM bulbs, they are that close in color, but when you looked close at the reflector headlight housings on my car, you could see the dark blue partial bulb tinting on the OSRAM bulb being reflected on those internal surfaces, and on the other side you could see the light blue bulb tinting on the PIAA bulb being reflected on those internal surfaces, and this is really the only difference you could tell out in the real world. Driving down the road at night, you couldn't tell that one side of the car was putting out whiter light than the other side, or that one side of the car was putting out more light than the other side. But, when I returned to my garage, and was shining the lights up on the wall, and just studied them for a couple minutes, to me it looked like the OSRAM bulbs were a tad whiter than the PIAA bulbs, and it also looked like the OSRAM bulbs were putting out more light/lumens than the PIAA bulbs (the "hot spot" looked more intense and brighter). So now, back to that "up to 3900K" that is printed on the PIAA packaging. For my OSRAM bulbs, I saw stated numbers (on the internet) of anywhere from 3400K up to 3700K, and personally I think they are somewhere in the middle, right around 3560K, so when I'm looking at these lights shining up against my garage wall, and to me it looks like the OSRAM is a tad whiter than the PIAA, then that "up to 3900K" statement on the PIAA packaging can not be right, or maybe the kelvin numbers for the OSRAM bulbs are way understated, and should be much higher. Either way, to my naked eye, it looked like the OSRAM bulbs were a tad whiter and brighter (more lumens) when shining on the garage wall than the PIAA bulbs, so the PIAA bulbs are in the process of being returned to Amazon, and I will keep the OSRAM Night Breaker Unlimited bulbs installed in my car.

Slight improvement over stock. One light dead within first month of install.

I was looking for a whiter looking light for the DRL/high beam on my Acura RDX. After looking at a handful of different bulbs, I decided to try these because they are a name brand and have a good reputation for quality. After installing one bulb, I noticed that it was about 2% whiter than the factory bulb in the other headlight. I actually decided to leave the other bulb in since I could barely tell any difference between the new PIAA bulb and factory bulb that is a few years old. I have used the Phillips Crystal Vision bulbs in one of my previous cars and believe that the Phillips may actually be a little whiter than the PIAA.I gave 3 stars because its a quality bulb that should last a while, just didn't look as advertised.

I've run these bulbs in several vehicles prior to my Civic. They are always a big step up from OEM. I have experienced relatively short lifespan in the past but that's the tradeoff for a bright white bulb that plugs in to your existing wiring. We'll see how it goes with these.

The product showed a crisp bright white image to highlight how bright the lights were supposed to be but they are not as bright. They are still good lights but not as bright as advertised. I love PIAA but these bulbs are just not bright enough as compared to the PIAA Night Tech that I have for another vehicle.

Very bright bulbs. The low beam with these new bulbs in are about as bright as the high beam with my old bulbs. High beams are crazy bright now! Although -1 because they're not truly white. They're a really bright yellow. Much better than a halogen yellow but still not as white as an LED bulb, but probably one of the best shades and brightness without getting an HID kit.

These bulbs are the best option for upgrading your conventional-bulb headlights. If you have rubber boots around the base of the bulb, those boots don't fit on LED replacements. I use these bulbs on my truck and motorcycles.

Not as bright as expected, very small noticeable difference from factory bulbs but anything was better than what they were.

Have these in my journey and are not at all bright. Can only see up to 8ft in front of me and no wider than my suv at most. Not worth it

1 bulb burnt out in the first three days. They were installed correctly by a professional. Hopefully was just a lemon.

ces ampoules ne sont pas au DEL alors je ne les installe pas, Ce sont comme celle que j'ai sur mon auto. Désolée

Quite frankly I expected more of a difference from my normal halogen bulbs. So far have not experienced that.
