Philips X-tremeUltinon LED HB3 / HB4 (Twin Pack)


A widespread problem in the automotive lighting industry is the increase of counterfeit bulbs in the marketplace. It can be difficult to check the authenticity of bulbs, but to counter this growing concern, Philips have given the consumer an easy way of determining for certain whether or not they have received genuine Philips products. Each of our products comes with a unique QR code that can be verified as authentic by Philips here.


(NOTE: The special 'HB' fitting of these bulbs allows for them to be used in either HB3 or HB4 applications. Purchase includes only one twin pack of bulbs with a multi-fitting base.)

An LED headlight that covers all bases: Philips’ new expertly designed X-tremeUltinon LED headlights offer style, safety, sight and long life in one distinguished package.

Why buy Philips X-tremeUltinon LED Headlamp HB3 / HB4 (Twin)?

The new X-tremeUltinon LED headlights range is the culmination of years of technological innovation, utilising a variety of Philips’ patented design features in order to achieve a headlight that surpasses expectations in every field. With the help of LUXEON LED technology, the bulbs achieve a bright white light with a colour temperature of 5800K, producing a 200% brighter light than that of a standard halogen.

What’s more, the stylish white light effect of the X-tremeUltinon LED headlights’ beam is designed with precision in mind, making use of SafeBeam technology to ensure that the bulbs’ extra light stays where it belongs: on the road. As well as being more distinctive than a standard halogen light, the white LED light produced is closer to the colour of natural daylight, helping you to stay alert and energised on the road at night. The refined positioning of the strong, uniform LED light enables you to see far-away obstacles on the road, without the risk of dazzling other drivers.

The expert craft of the X-tremeUltinon LED headlights range also means that you can enjoy the benefits of a brighter, whiter light for longer. Philips have implemented advanced AirFlux and AirCool technologies to increase the bulbs’ heat resistance, diverting heat from any critical components, thus extending their lifetime. These intelligent heat management systems, combined with the higher light intensity level of the LED, make for an impressively durable bulb with a remarkably long life of up to 12 years.

With the X-tremeUltinon LED headlights' easy installation process you can enjoy extra sight, style, safety and bulb-life in no time at all. Get ready to outshine and out-style the competition.

PLEASE NOTE: These foglights do not have ECE approval, and as such their usage is currently not approved for use on public roads: their usage is limited to ‘off-road’ applications. In addition, their installation may trigger a bulb error message to appear on the vehicle's on-board computer system / dashboard. This is a harmless side-effect and may be removed by installing a Philips CANbus Control Unit.

5Philips X-treme LED

I used Philips "Diamond Vision" bulbs for the Dipped & High beam on my MX5 (four head lamp system). The dipped beam worked very well, but High beam was poor hardly making any contribution. I wanted an improvement & the best, so I purchased this twin pack which was not cheap. I glad I did as I was not disappointed and shocked at how much power these have, also correctly focused. It says on the box 200% more power than Halogen, I would say more like 400%. I have tried HID before and couldn't get on with poorly focused beam. The kit was easy to fit, just make sure you get the polarity correct. The only gripe I have is that the fans at the back of the bulbs had surface rust - may be it was stocked for some time. This was easily remedied with a bit of black paint. Overall the best lighting upgrade I've seen.

The dipped beam halogen projector of my RAV4 2014 is very picky with regard to aftermarket LED bulbs. I tried a much expensive Japanese brand from a US seller, but the results are not good, and not even comparable to stock in terms of beam throw and pattern. The bulb ended up to my main beam. I saw this Philips HB3 at Powerbulbs, it’s quite expensive but decided to bite the bullet. Glad I did, they light up the road much better than the stock. The bulbs are truly within the standard halogen bulb light pattern with a clean white light and sharp cut-off. The light is even much wider and the beam throw (how far you can see ahead) is excellent. Build quality is also great. This bulb will not disappoint you. My only concern is the bulb longevity. If the bulbs last even half of the claimed 12 years life expectancy, I’ll be happy with it. Only time will tell. Thank you Powerbulbs!
