In no case are they white as described. I bought them to bring the position lights closer in color, with the Philips H1 and H7 (high beam and main beam) which are excellent. The blue casing gives you the feeling that it will be white knowing that it is K4300 but it tends to end up almost yellow. If I knew that, I wouldn't have chosen them as they are far away in color

If you choose them for "headlight lice" and you have LED or xenon in the main lights, they make a difference.
It is not the white that the product describes...
It is in the 4200 color of lighting.
Otherwise, they are branded bulbs with obvious durability...

I should have listened to the reviews more. I bought them for the license plates. They are a shade whiter than the typical ones, but not a big difference. The brightness is as expected. I wouldn't buy them again, they're not worth the premium price. They don't fit on the canvas. I hope at least they will last over time and I won't have to deal with them again.

P.S. I have tried to install (Philips and non-Philips) LED 6000K, but they don't fit on the canvas.

I bought these specific bulbs to color match them with the WhiteVision Ultra bulbs I have in my main lights. The color is quite white for a halogen bulb and the brightness is as expected. If someone wants higher brightness, they should go for a more yellow bulb. As for durability, I don't have an opinion yet.

No xenon effect. They have yellow light. Finally, the 4300K are very few, if they are true, because they are not mentioned anywhere on the packaging.

I bought them to replace the one bulb that burned out after 15 years. Their light is yellow, but much less yellow than the classic w5w bulbs. A good solution for those who don't like the terrible blue LED bulbs that constantly burn out! I have had them for 3 years already without any issues. If they burn out again, I will buy the same ones.

I bought them for the license plate on my golf mk7 because every LED I have tried messes with the can bus. The lights are yellow and have blue glass, but the light is not white at all. It's a waste of money for someone who wants them to look like xenon, LED.
