Philips Racing Vision GT200 H7 Headlight Bulb +200%, Double Set,

Product Information

Bulbs arrived on time as promised and well protected, after replacing one bulb and comparing the difference between the standard bulb and these upgraded bulbs the difference was more than noticeable, ideal for country lanes during winter.

With the capability to withhold increased pressure inside the lamp, UV-quartz glass is able to produce more powerful light. This bulb is by far the brightest halogen headlight bulb currently available which brings you a rally bulb that can be legally used on a public road. It’s an unusual, if not unique, set-up, but the results have been corroborated by tests at parent company Osram’s conventional light tunnel in Germany, which we have used in the past. With their optimized high-precision filament geometry, up to 13-bar high-pressure gas filling, Philips RacingVision headlamps boost your visibility with up to 150% more brightness,set a new standard in automotive lighting.

After installing into my wife’s Mazda 2 and waiting for darkness, we both agreed that they were an improvement over the existing (pretty much standard) bulb - but not anywhere near as good as we had hoped. Philips may have taken both wins here, but it has not all been plain sailing because a poor sample, which failed to meet the minimum ECE light output, meant we did not rate the Xenon Vision.

In the light lab there was a good spread of light, with a clear hot spot close to the 75-metre mark. Environmental concerns over the mercury they contained have seen the focus switch to D3S since then, making it the biggest seller in the aftermarket, with growing sales as cars fitted with them reach the end of the five-year life of the lamps.Please use our online xenon HID bulb finder if you're not sure which HID bulb fitting you need in your car.
