To achieve the utmost style and performance from your signalling bulbs, upgrade to Philips’ X-tremeUltinon gen2 Amber LED today.

Why buy the Philips X-tremeUltinon gen2 Amber LED WY21W (Twin)?

With the Philips X-tremeUltinon LED range achieving worldwide praise since its entry into the automotive lighting industry, the X-tremeUltinon gen2 range is a welcome addition to the Philips catalogue. Confirming Philips’ reputation as pioneers in LED lighting, this new and improved second generation range of LED bulbs offers immense style, performance and lifespan in one comprehensive package.

As with its predecessor, the X-tremUltinon gen2 LED range features only the most innovative technology and state-of-the-art components in its assembly. The Philips team’s masterful engineering is present in every aspect of the bulb, which offers not only an intense amber signalling light, but a sturdy casing, able to withstand even the harshest of environmental stresses such as extremes in heat and vibration.

Along with an intense, stylish light output and resilient design, the X-tremeUltinon gen2 boast an efficiency unrivalled by other lighting technologies. Philips’s grasp over the latest developments in LED technology allow these X-tremeUltinon gen2 bulbs to use only a minimal amount of energy while still producing a stronger light than halogen technology, thereby extending the bulbs’ lifespan up to an incredible 12 years.

And with a simple plug-and-play design (which includes a CANbus adapter), installation is a breeze. Make a purchase from the Philips X-tremeUltinon gen2 LED range today and experience high-performing LED lighting for minimal effort and cost.

(Though these LED bulbs can be fitted to any WY21W fitting – inside or outside the vehicle – their usage in an exterior application is not road legal; such usage must be confined to off-road driving.)

Great site.


Unfortunately I ordered these in error for my Skoda Superb. No problem with powerbulbs to return them. I ordered the correct py21w Philips bulbs and they're fantastic, very bright and easily seen.

Great bulb


Great outcome and nice design. Unfortunately the installation pamphlet guide wasn't too clear. I had to cut/splice cables, it's not plug and play but in the end I install them without knowing much stuff in car electrical system. The look and light output is nice.
