Auto Express Review - BEST BUY, November 2011
"Precise positioning of the filament explains the performance of the plus 100 per cent X-tremeVision. Every bulb is inspected, which is why it’s so pricey. But it pays off, with a bright hot spot nearly 75 metres away."

Product history:

X-treme Vision has now replaced the multi award winning Xtreme Power. The original X-treme power gained itself an excellent reputation by winning the ‘Best Buy’ award in Auto Express between 2007 and 2010. This was given due to it’s performance and endurance. The new Xtreme Vision now gives 100% light on the road, 20% more than its predecessor which gave 80%.

Are they legal to use and do I need to modify my vehicle?

The bulbs are fully road legal and no adaptations or modifications need to be to your vehicle. The bulbs are directly interchangeable with your existing bulbs and are just a straight exchange.

How does the product generate more light when the wattage is standard and are they safe to use on plastic lenses?

X-Treme Vision use a halogen/xenon gas mix and a refined design of the filament. The xenon gas is a very efficient and produces a brighter, whiter light than when halogen gas alone is used. This means that the bulbs have a greater output of light on the road. The bulbs are all standard wattage, this means that they are completely safe to use with plastic lenses and they are fully road legal.
