Bought these for my wife’s Nissan Juke . The original H4’s are a horrible dull yellow .. these replacement Osram cool blue are an immediate transformation to a nice crisp white with a hint of blue .and can actually see your light on the road now .. very pleased

4 OSRAM Cool Blue Intense H4

These produce a great light, but they only lasted 10 months with normal use. By normal I mean 1-2 hours a week during daylight saving and 3-4 hours a week out of daylight saving.

5 Lasted four yrs with ignition on use.

I use these in my 2005 Infiniti G35. Headlights and foglights (this H4 is the fog) are on at all times if the ignition is on. I don't have DRL lights. The G35 seems invisible to others without the lights on. I first used these exact bulbs in 2014. They lasted until early 2019. An amazingly long time with excellent brightness. Power Bulbs has excellent service/prices and the bulbs arrived from the U.K in about a week.

5 Greatest update for headlamps

good throw in light, the higher 4200k seems to reflect objects better than the new Night Breaker Laser (NBL). i was using Cool Blue, then tried NBL for two weeks. found the light in NBL not as good(to the point i often checked if the low beams are turned on), thus revert to cool blue intense. thanks powerbulbs for sending well bubble-wrapped packages! totally recommended as a first upgrade that meets style and performance.

5 It does exactly what it says.

I have these bulbs for a month+, so I can't say anything re. durability. However, compared to my 'old' standard bulbs, these ones produce a lot of extra light. Good and clear beam and the color tends to white, not blue, just as it should. Very happy with this upgrade. Delivery was fast. A+

5 Mini Cooper F56 upgrade

Perfect upgrade to replace regular yellow halogen bulbs, highly recommended they give a clean white light with slight blue hue! Worth changing all x3 sets main beam, fogs and side lights. Great value for money!

4 Osram Cool Blue Intense 9003

Product shipped on time & arrived when expected. The light output is better then expected as higher Kelvin bulbs do not put out as much usable light as conventional halogen bulbs. I installed the 9003 bulbs in new assemblies and only used them for a few hours, in non-incliment weather. I say the bulbs are great if you want a whiter light halogen replacement for your standard halogen. I'd be real impressed if the life expectancy exceeds what is printed on the box. Osram hasn't made any unrealistic claims. The bulbs was purchased to accent the 2500K axillary lighting I added to my vehicle, and delivered the disered results.

5 Crisp White Light! - Swift Sport 07.

I based my purchase choice on other reviews on here so thought I would post my own. First of all the delivery and service of Powerbulbs was superb. A+. I ordered on Thursday and received my package Monday morning (UK to Ireland) which was extremely fast. I bought these alongside Cool Blue Intense W5W (501) for my sidelights and reg plate. The result was exactly what I was looking for, increased visibility and a crisp white light. These do not have much of a blue or yellow tint they are a simply a really crisp white - really transformed the look of my Suzuki Swift. For the price I cannot recommend these enough. They are also road legal which was a main point as I didn't want to go changing them each NCT/MOT.

5 New bulbs

I am very happy with my purchase, the first night I noticed how much further I could see. I would recommend to anyone. I don't use high beam much (unlike other people at night) but when I need to the difference is quite noticeable. Cheers

5 2005 Honda Jazz, upgrade to OSRAM Cool Blue Intense

Bulbs are as advertised; shine further and brighter than the stock bulbs. The longer beam gives you more time to react as you can see further ahead. I would recommend these bulbs.

5 Bright and clean

new bulbs fill all those close in dark spots where cyclists and pedestrians can be hidden, and this without blinding oncoming traffic. Worthwhile investment.

4 great stock replacement bulbs

These are great bulbs, whiter (yellowish white),brighter and wider beam than stock bulbs. i think this should be named cool white intense instead of cool blue intense, as there is no bluish light.

By Martie on

OSRAM Cool Blue Intense H4 (Twin)

4 Excellent

I wouldn't say they're easy to mistake for HIDs, but they do give an excellent, pure white light without any yellowness. A massive improvement from standard halogen bulbs. Only downside is if you have dim-dips, in which case they do have a slight yellow tinge, but that's easily cancelled out with the right sidelights.

5 Wonderfull bulbs in the night!!!

I've tried the H4 Philips Blue Vision Ultra (4000K) and these Osram H4 Cool Blue Intense (4200K). Both have exactly the same bright seen in front of the vehicle. But, Osram has a hint of blue in the headlights more beautiful than Philips, particularly when they are turned on. When driving in the nigth, Osram has more white light than Philips, almost identic the HID. It's amazing. I declined to the Osrams, cheaper than philips and made in Germany. These bulbs are an excellent choice. Buy it without hesitate.
