PhilipsWhiteVision ultra H4 car headlight bulb, 4.200K, set of 2

Swapped out my old bulbs for these and the difference is noticeable right away. The light is whiter and clearer, which makes night driving feel safer and more comfortable. They’re not full LED, but they give a nice modern look without blinding other drivers. Installation was straightforward too. Took off one star because they’re a bit pricier than standard bulbs, but overall—worth it if you want better visibility and style

Good quality bulbs easily fitted to FL2. Whiter light so need change both as a pair ( number plate lamp)

Had these before and they were definitely brighter, but didnt last nearly as many hours as they should, according to the lifetime expectancy. This time the pack contains not just the dipped bulbs but two others, which look like high beams - nothing in the description about that. Will see when I replace them whether they are high or side beams.

These bulbs are excellent! They have a nice whiter light (not perfect white but halogen can't really ever be perfect white), and they are insanely bright. They aren't the longest lasting bulbs but thats to be expected from such a powerful bulb. I had a pair of these in my old car and they lasted roughly 18 months before giving up the ghost. Personally thats worth it to have such a bright safe light in the dark.They were easy enough to install but thats on a car by car basis. On my golf they're easy to get in, once you've removed half the front of the car and have the headlights out on a bench. You can't go wrong buying these bulbs.One word of caution though, when installing a halogen light, try to avoid touching the glass portion of the bulb as grease from your fingers decreases their life span. I used latex gloves while fitting mine.

Nice item at a nice price Working a treat i recommend to all.

Fit perfect on my Hyundai i30. Now is much better to drive in night time.

Bought two sets of these. They are really bright, but the first set lasted 5 weeks. Thought that was maybe a bad batch, however the second set lasted just a little longer at 8 weeks.

This review is for the HB3 fitment, installed on a 2019 Honda Civic.I bought these bulbs to compliment the LED day time running lights and low beam LEDs (also Philips). Unfortunately, whilst I realistically did not expect these to match the colour temperature of the above, which are typically around 6000K, they are actually slightly more yellow than the standard fit Sylvania 'basic' bulbs supplied with the car, with no noticable improvement in projection distance either. As such, this product feels like an expensive downgrade on the previous set up.The problem lies wholly in Philips misleading marketing, which claims 4200K for their WhiteVision Ultra series, unfortunately, if you examine the small print (not covered on Amazon) this only applies to their H7 and H4 fitments. Actual technical data (again, buried deeply within the Philips website), only states 'up to 3800K', which given the overly warm colour of the bulbs, I would say is not even close.Overall, I'm dissapointed to say the least and will give Philips automative products a wide berth in future.
