LED innovation for people passionate about driving

The Philips X-tremeUltinon LED gen2 sets the new performance standard for LED retrofit. Unique Lumileds Altilon SMD technology, as used by car makers, provides 250% brighter, whiter light for safer, more comfortable night-time driving.

IMPORTANT: This LED retrofit light is specifically designed and intended for off-road use only, such as fally and race track driving. The LED retrofit light cannot legally be installed in on-road vehicles. It is your responsiblity that the use of the LED retrofit lights complies with applicable legal requirements. Designed for rally and race tracks. Not for use on public roads

Get up to 250% brighter light for superior visibility

Driving in the dark is demanding, so you rely on your headlights to keep you safe. With its intense bright white beam, the Philips X-tremeUltinon LED gen2 headlight is pushing the boundaries of light, improving visibility by up to 250% to help you see farther. Thanks to its unique, premium Lumileds LUXEON Altilon SMD LED chips, as used by car makers, you'll experience an unrivalled daylight-like effect when driving at night. And because you can see more, not only will you be safer, you'll also enjoy a more relaxed, comfortable night-time drive.

Unique OEM Lumileds LED chips for superior light performance

Philips X-tremeUltinon gen2 is the only aftermarket retrofit LED using Original Equipment Manufacturer (OEM) LED chips: Lumileds LUXEON Altilon SMD. The superior light performance includes an extremely sharp cut-off line for a perfect beam pattern. This means the beam accurately illuminates what lies ahead without dazzling others, keeping you safer in the dark. One of the reasons why Lumileds LED chips and Philips headlight bulbs are chosen by the world's major car manufacturers is because they're fitted with the very best components, giving you the very best performance.

5800-Kelvin colour temperature for cool white light

With a colour temperature of up to 5800 Kelvin, the Philips X-tremeUltinon LED gen2 headlight produces a bright white, daylight-like beam. Today's new cars have headlights with around the same colour temperature because this is proven to be the most appropriate for the human eye and for seeing warning signals. With clearer vision, you're better able to spot obstacles and take the perfect driving line. And as you don't have to strain to see the terrain ahead, brighter lights make for a more comfortable, exciting drive.

Powerful bright light, directed exactly where you need it

The best headlights are not simply the brightest. Creating ever-brighter LED bulbs for cars is easy; it's what you do with the extra light that matters. Uncontrolled bright light is not ideal for driving and can create dangerous glare. Featuring SafeBeam technology, Philips LED headlights concentrate light exactly where you need it. The uniform, accurate beam pattern is designed according to road-safety regulations for halogen headlights. Precisely controlled light gives you greater visibility, making you a safer night-time driver.

AirFlux and AirCool heat management for hot-lumen stability

Heat management is a critical factor in the performance of LED lights. The X-tremeUltinon LED gen2 is equipped with AirFlux [~H4 and Fog] and AirCool [~H7] heat-management systems. These dissipate heat effectively, ensuring the headlights always perform at the optimum brightness (lumen stability). Because they use less efficient heat-dissipation technology, many competitor LEDs emit a weaker beam of light when they get hot. The X-tremeUltinon LED gen2 doesn't have this problem, because it allows heat to escape quickly. You get a consistently powerful beam of light throughout your journey.

CANbus adapters keep your car's electrics working smoothly

Some car models present particular challenges for LED-based retrofit lamps, such as faulty dashboard warnings, flickering lights and high-beam indicator issues. Unique Philips CANbus adapters solve these problems, ensuring you don't experience any of these electrical glitches and your LED lights work as intended. Thanks to its advanced design and robust housing, the CANbus adapter is easily installed and designed to handle the demands of daily driving.

Matchbox-sized LED driver box makes installation easy

Equipped with a smaller driver box (which converts high voltage to the low voltage required by LEDs), the X-tremeUltinon LED gen2 can fit into even the smallest of headlight units. Now smaller than a standard matchbox, the LED gen2 is easy to install, whatever vehicle you drive.

Durable headlights that can last as long as your car

You want bright, stylish headlights but you don't want to keep replacing failed lamps. That's a major weakness of conventional headlights; the more powerful the light, the shorter its lifespan. At a higher light-intensity level, LEDs last much longer, and Philips X-tremeUltinon LED gen2 headlights are built to last. Due to features such as AirFlux and AirCool heat-management systems, they last up to 12 years. With most cars replaced or upgraded within that time, your stylish new headlights should last the lifetime of your car.

Narrow tolerance ensures compatibility with existing LEDs

Both OEM LEDs and Philips X-tremeUltinon LED gen2 are manufactured to a narrow tolerance around 5 800 K. This enables them to work alongside existing LED bulbs on your car without causing clashes in light colour. So they'll fit perfectly with your daytime running lights, for example. Put compatibility concerns behind you with Philips X-tremeUltinon LED gen2.

The durability that today's drivers demand

IP65-certified against dust ingress and with splash-water protection, Philips X-tremeUltinon LED gen2 are also guaranteed EMI-compliant, conforming to automotive-industry standards on electromagnetic interference. Precision-engineered to withstand the rigours of modern motoring life, they offer the durability that today's drivers demand.
