Philips 9006 X-treme Power Headlight Bulbs (Low-Beam), Pack of 2

I bought the Philips X-treme Power 9007 to replace the OEM Sylvanias in my wife's '01 Mustang GT. She was complaining about being unable to see well at night. The headlights definitely were dimmer than when the car was new. Her first reaction to these bulbs was "woohoo", and we both agree the headlights are as good as new. The low beams look white, not blue or yellow, and do not bother other drivers.The rest of this review is a little technical, and it may help some readers understand why other reviewers report that these bulb aren't so great.I had 3 options that I could have taken separately or together to improve the headlights:1. Replace the headlight wiring with a heavy duty harness switched by relays and delivering about 14.2 volts directly from the alternator. This would have driven the OEM bulbs harder than the stock setup which was delivering 13.05 volts to the low beams. But I figured 13.05 volts should be adequate, knew my electrical skills were only average, and didn't like the risk of a relay failure. At 14.2 volts my OEM bulbs would have been 33% brighter, and I'm sure that would have been enough. Upgrading the wiring is a good option for some cars and mandatory for cars that have a more significant voltage drop than mine. If my electrical system was delivering only 12 volts to my bulbs, then these higher performing bulbs would not have helped enough.2. Refinish the polycarbonate lenses of my headlight fixtures. I might do this some day because the lenses are moderately sandblasted and slightly cloudy. Refinishing would have consisted of two or more steps of wet sanding followed by polishing to remove sanding scratches and sealing to protect the refinished lenses against UV light. I chose not to do this because the car isn't driven much and stays in a garage where the UV exposure is minimal, plus I'm not impressed by the durability of the sealants on the market. I think the best of the bunch is the sealant that comes with Glassylite's restoration kit, and I hope there will be something better in a few years when I really need it for this car.3. Replace the OEM bulbs with high performance aftermarket bulbs. This is what I did, and it involved some guesswork. I knew that to be DOT legal 9007 bulbs must produce between 850 and 1150 lumens at 12.8 volts in the low beam position. I knew that due to the halogen regenerative cycle the car's OEM bulbs were about as good as they were when new; the loss of output was due to the deteriorated condition of the lenses and possibly to an increase in the voltage drop of the headlight circuit. I guessed that the OEM bulbs were somewhere near the low end of the DOT scale for 9007 bulbs, and that the Philips X-treme Power bulbs were somewhere near the high end. My hope was that the difference would be great enough for me to put off doing step 2 or step 1 above. I guessed correctly.I did nothing else to my headlights other than backprobing with a multitester to measure the voltage drop and cleaning the lenses. Cleaning the lenses helped a little, but major credit goes to these bulbs.If your headlights are dim due to a serious voltage drop, then buying these bulbs will be like solving the wrong problem. The same is true if your lenses are very cloudy. However, if you have decent voltage, reasonably clear lenses, and average or below average performing 9007s, then you will appreciate the difference these bulbs make. Compared to my car's OEM Sylvanias these are brighter, whiter, reach out farther, and spread light wide enough to make cornering easier and safer. Other drivers are not offended by these bulbs, so the bulbs are a win-win. Installing them was far easier than changing the wiring harness or refinishing the lenses. So they deserve 5 stars.

Philips H13 9008 X-treme Power Headlight Bulbs, Test drive and price invoiceSpeaking of Halogen Bulb Replacements,I tried to say as much as I can below so others will hopefully get a good understanding of what to expect.I read the other Threads/Post here and decided to do a separate Thread.This way this one is just for discussing the Philips replacement halogen headlight bulbs.I did a lot of reading on multiple internet sites about the Philips as well as a lot of others.What I come to find out was many of the bulbs are a Joke.They may look cool but don't really offer any real improvement to you seeing better.Also I found out that there are those bulbs out there that will Melt the Stock Socket/wiring harness.The Philips is one that is made in Germany and does keep very close to it's specs.Meaning it is not going to Melt the Stock parts !!!My conclusion is this.I went with the Philips because after reading and talking to a tech on the phone.He actually did try the Philips on his wife's vehicle.And what I heard from him really impressed me.It went something like this.The Philips does provide better lighting but it is not some great big improvement.But if you get out there where there is No-Street Lights or any Lighting at all where it is actually Dark.You can tell there is a benefit with the Philips.It provides better lighting to the sides as well as in front.But it is as I said not like HID or Xenon lights just because you changed to the Philips bulbs.But if you actually want a bulb that does have an improvement and will not "Damage" the factory socket or wiring these bulbs are a good choice.So after talking with him over at (Candlepower Inc.)I decided to give the Philips a try.Last night the wife and I took the MCS out and drove it for awhile at night.after we drove it for awhile we felt like we knew what the stock halogen lights were like.So tonight we waited until dark and off we went again.My wife said I see a difference and this was when we were still in the subdivision.We then drove on two lane roads as well as the interstate.We actually drove on two different interstates.Now to the point in what we both actually think.There is better lighting with the Philips.What percentage I honestly can't say.It is better but not some great big huge change.Our opinions are the lighting is (Whiter) not as yellowish looking in front on the road.It is also a Brighter light on the road but (Not-Drastic) at all.Is it noticeable, yes !!!All the above comments are speaking of using the (Low-Beams) only.Now speaking of the (High Beams).That is pretty bad ass for sure.They work "Great" !!!You can actually LIGHT up the road way-up in front of you.Very-very nice for sure.And a very good pattern as well.We tried them on a two lane country roads and they just lit-up everything in front.Way-Way in front of the MINI.Before I forget to mention this.I went by my Mini Dealership yesterday and had them (Raise) my lights up some.They seemed to me to be right down in front of the MINI.Way to close so after they raised them they now are out in front more so.Not way out there but certainly better than they were.Let me explain this in this manner.I don't think they (Low Beams) could be raised up any higher and here is why I say that.When you go to High-Beams they are right exactly where they belong.Not up in the trees.They are way out in front of the car but not to high.(High Beams)So that is why I don't think the Low Beams could be raised any higher than they are now.I know the majority of you know this but maybe there are a few members that don't.We have a (Single Halogen Bulb) for (Low & High Beams)So when you raise the low beams you are also raising the high beams.I think mine are dead on for both.Bottom-Line:I would tell another person these Philip Halogen Bulbs do work for sure.But Do-Not purchase them thinking you are going to see some Great-Big change in the lighting.That is just honestly not the case IMHO.Especially if you are driving where there are outside lighting.Like in the City as an example.Get out where it is Dark and you will see an improvement in Low Beams.But when you go to High-Beams it will most surely be obvious.And you don't have to be concerned over (Burning) any of the Stock components up.Sorry No-Picture of invoice but here is the Total Price.$63.70 Total

Great product
