Philips WhiteVision ultra H4 car headlight bulb, 4.200K, set of 2

Replacement for original headlamp bulbs, improved night vision, super bright. Great price.

kept getting flashed at to dip lights.... got annoying after a wile, the car has now gone... but i would not buy again only because i was fed up of people flashing at me. but the bulbs where of good quality and are a bright bulb just my preference to to re buy

If you want the white LED look, then these are definitely the bulbs to buy. They are super white! My photo shows the Phillips WhiteVision Ultra versus my daytime running light (it is NOT the yellow indicator!). I honestly don't think they are much brighter than the cheap brownish H4 bulbs, but they definitely look nice. With no rain the road is more visible. However, super white headlights cause the "backscatter" effect when the white light hits rain droplets, fog, or spray and reflects the light back toward the driver’s eyes instead of continuing down the road. This effect is much less prominent with slightly brownish (warm) headlights. The optimum colour headlight to reduce backscatter is around 4200 K. I started replacing my headlights each year (when I get my MOT) so they never burn out at an inconvenient time. However, I'll buy 4200K lights next time even though I really like the super white light from the Phillips WhiteVision Ultra.

Fitted a set of these to my Volkswagen Transporter (2013 T5.1) - they were a doddle to fit. They are certainly an upgrade over the stock bulbs, but don't expect miracles - these are not Xenon or LED levels of brightness and the colour to my eyes is off white (I have LED bulbs fitted in the DRLs and they are pretty close, but different). I was a little disappointed with the brightness when dipped. They are however excellent when on full beam. Longevity remains to be seen but I have done several evenings of long motorway drives so far without problems.

Bought these 3 years ago and they are still going strong! Would highly recommend, cannot fault them!

Purchased Phillips lamps as been in the industry for many years ,used the brand as a leader ,unfortunately after only 3 months the lamp has failed ,high beam is fine. I removed the originals as I live in the county with no street lighting . I would used again but really need to last longer .

The colour of the light is between white and light yellow

Not white it’s a yellow light

Best thing I did was buy these lights. So much better than origional specified lamps. Colour is good to see and a definite improvement in the light output. The park light replacement bulbs are a great bonus.
