Philips Racing Vision GT200 H4 Car Headlight Bulb +200 Percent, Set of 2

I have these in 2 cars now. One set replaced Philips Extreme Vision +130% with glass patterned lens and the other set replaced Osram Night Breaker Laser +150% with a complex reflector (plain lens). Both are H4 fittings. I've noticed Osram bulbs have a shorter life, hence changing to Philips. Both cars had more and whiter light with an even sharper beam image with GT200. There is less colour variation between dip and main with Philips. I tried an 80/100 watt standard technology bulb to try but modern high efficiency bulbs illuminate better. They have a better beam image and less glare leaking above the cut-off line. EXPERIENCE The older car has slightly degraded electrics and only produces 14.0 volts at the bulb compared with the 14.2 volts of the newer car which ran Osram previously. The older car still has GT200 bulbs. One of the GT200 bulbs in the newer car became defective after about 2 months. Both filaments operated at the same time as though connected in series and at low intensity. Fault was definitely the bulb so I swapped in an Osram which was not as good but made a reasonable pair. It was the Osram +150% which failed 18 months later- the other GT200 still works despite 18000 miles of mostly night use. This time I fitted longer lasting Philips Xtreme Vision +150% due to needing to remove bumper skin and headlamps to change bulbs. When I changed from Philips to Osram, that headlamp aim became low. Now changing from Osram to Philips, that headlamp is aimed too high. Changing Philips to Philips does not change beam height. SUMMARY GT200 are the best performing bulbs I've tried and are not hugely behind some newer cars which use LED lighting. They illuminate the road very well in dry conditions but obviously not so well in wet conditions. For wet conditions, only LED or HID gas discharge is truly satisfactory but the heat produced by halogen bulbs ensures snow melts in winter conditions. That is invaluable in the few days of snowfall which Britain may experience. Philips LED Pro 6000 sidelight bulbs match GT200 colour well. See closeup pictures for differences. Pic with 3 bulbs is (Left to right) Osram +150% (blue to base of bulb), Philips +130%, GT200. GT200 has cutout sections of dip beam filament blue filter. The integral fitting collar on Philips bulbs seems to be fitted more evenly.

Bright clean light aids driving even when under street lights. Non worry about glare or dazzling other road users. An easy swap for existing bulbs, just double check the type and yiur installation. I can't comment on longevity, yet.

They’re bright but they don’t last too long so switched to LEDs yes 3 times the cost but at least they last forever. The downside of that is you need to swap back for these for an MOT. So you’re still swapping them annually but that’s the crazy world of government red tape I guess

Got these for my Nissan Note 07 and they done a perfect job! They are the exact same with all the same fittings which made it really easy to install and replace my broken ones. They are a super bright colour so even on an older car like mine they done a great job and they are not expensive compared to some others you can buy. I am not 100% sure how long they last but 6 months in and they are going strong with no signs of blowing.

They are noticeably brighter than standard H7 bulbs but not up to the kind of brightness you get with led bulbs. They are however a legal improvement for the UK. The are a lot of money for a relatively small improvement. Perhaps with older bulbs the difference after changing maybe more. My headlights bulbs were less than a year old.

Great upgrade from standard bulbs provided better illumination with a bright white light. Good value replacements

Have had Phillips head lights before, and true to form these are excellent, great throw of light, makes night driving so much easier. Well recommended.

An over all brighter light than the cars original bulbs which was a plus. However, after 15 months, of very little use, the low beam filament blew on one side and three days later the other side had the same failure. I would therefore not recommend these bulbs, nor any of this manufacturer items, due to the poor longevity and quality issues.
