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. Read more here.

Offering vast and intense illumination, the new Philips X-tremeUltinon gen2 is a technologically accomplished revision of the enormously successful X-tremeUltinon series.


Why buy Philips X-tremeUltinon LED gen2 Fog Lights H4 (Twin)?

As with Philips’ highly regarded first generation of X-tremeUltinon bulbs, the new X-tremeUltinon gen2 achieves both a strikingly stylish LED light colour alongside a vastly improved projection of light. Where the original headlight range offered a 6500K white light, up to 200% brighter than standard, the X-tremeUltinon gen2 favours an even higher performing light output without sacrificing style.

The Philips X-tremeUltinon gen2 is able to produce a magnificent light, up to 250% brighter than standard, while retaining a classic cool white LED light with a colour temperature of up to 5800K. Such an expansive projection not only heightens your presence on the road at night, but also ensures you notice potential hazards and obstacles much earlier than normal. Meanwhile – owing to Philips’ use of premium Lumileds LUXEON Altilon SMD LED chips – the X-tremeUltinon gen2’s crisp white projection achieves a look of supreme style, managing to be both visually striking and optically comforting.

Thanks to Philips’ scrupulous eye for detail and world-class engineering standards, the X-tremeUltinon gen2 are also designed with longevity and resilience in mind. By implementing their patented heat-management and cooling technologies (AirFlux and AirCool, respectively), Philips have designed a bulb capable of defending itself against extreme weather and overheating. This, alongside the bulbs’ durable, shock-proof design and energy-efficient LED technology grants you an amazing bulb lifespan of up to 12 years.

Of course, the lifetime, style and strength of a light mean very little if the beam itself doesn’t reach its target – the road. Thankfully, with the X-tremeUltinon gen2, Philips have implemented their own renowned SafeBam technology, ensuring the road ahead is captured perfectly in the beams’ projection, and other drivers on the road are not dazzled by the bulbs’ massive expanse of light.

Make the change to Philips X-tremeUltinon gen2 today, and enjoy long-lasting, tremendous improvements both to your vehicle’s lighting performance and style.

PLEASE NOTE: These headlights 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 of the low-wattage LED bulbs not being recognised by the vehicle's CANbus system and can be solved with the installation of an additional Philips Canbus Adapter

For a detailed specification of this Philips X-tremeUltinon gen2 fitting and its features, along with comprehensive installation instructions, please find the product manual here.

Huge improvement


So. I bought a new old car. Mazda 2. Couldn’t see a hand in front of my face - or - an unlit cyclist coming toward me Bought these, having got old, and having tried the super halogens before (they fail after six months of heavy use) Initially disappointed, but a trip to garage to reset headlights was well worth another tenner Far far improved, white lovely light. Easy install , everything included. And great advice from powerbilbs

Excellent LED's


Have had these fitted for over 2 months now. very easy to fit. They have spectacular performance. I replaced PIAA halogen which I thought were good and was amazed. Only small grip is the cut off on the top of the beam is not as defined halogen.

Pretty good


Installed these in a 2008 Honda Element.I did a a comparison of before and after with a halogen installed vs this new Phillips LED H4 using a black panther headlight aimer. The light pattern of the LED is very similar to the halogen which is great and what you want unlike led's of the past that spew light all over and not where you want it like into oncoming traffic. The light is a nice white and hopefully the brigtness will last a lifetime. One thing I did notice on the aimer is both sides were equally high slightly and had to be adjusted down so I recommend you take to a shop to have your aim checked. Fit and finish of the product was great, no issues there, no fans to make noise or interfere with radio stations. On the road now for just over a month and pretty happy with these. They are brighter and I hope last for years and don't degrade like a halogen bulb. One minor limitation I see is the high beam, it tends to light up great more to the sides but not as far directly ahead of you. Again I think this is a design limitation of this LED being mounted on a board vertically, even with the deflectors it just can't make the light shine straight up because there's a circuit board in the middle of it. It might not be as good as a new halogen in this respect. It's still better than the old LED bulbs of the past that shot light all over the place and didn't reflect it properly using the housing. Don't even consider an LED bulb that doesn't replicate the design of the original halogen, it just doesn't work well. One other thing to consider with this LED bulb is you may or may not have daytime running lights anymore, it just depends if the low voltage that normally would light a halogen up dim during the day will light up these LED's. That's something to consider because in this day and age as drivers become more dependant on their vehicle doing everything for them. (Like those people that drive at night with only DRL's on that somehow the headlight switch came off auto) they might not think to turn on the headlight switch. That's not an issue for me considering I get better lighting more when I need it at night and if I encountered adverse weather conditions during the day that I feel required greater safety I can just turn the headlight switch on. All in all a great light so far after almost 2 months and hopefully the last bulb I'll buy for this older vehicle.
