Owner of the product for about a year without any problem. The installation was easy.
I have installed them in a Renault Megane 4. I had to buy an adapter because otherwise they wouldn't fit in the projector.
You can search the text to understand what I mean. (Car LED H7 Headlight Adapter Bulb Holders Auto Lamp Light Clip LED Base for Renault Megane). Cost 2 euros.
As for the performance, they are slightly better than the halogen bulbs that were previously installed, but it's not the difference I expected. However, I prefer their white color over the yellow.
In terms of value for money, you can't expect high-end models.
Next time I buy LED lights, I will prefer to spend a bit more for something better.

In Seat Leon 5f with a regular headlight, there is not much difference compared to a regular halogen bulb. These specific ones will be preferred by someone for the color they emit rather than their performance. You will also need a separate canbus canceller so that it does not give you a warning.

In a lantern with a mirror, they do not have a high intensity of illumination or a long beam.
Compared to simple factory halogens, they definitely make a difference but not what I would expect.
Possibly the model with the highest wattage may have better performance.
Their color is cool white as stated and the response is immediate as they are LED.

I saw the real light. Strong white light, I don't think it blinds others, easy installation on a motorcycle without canbus. I have no opinion on canbus. The durability over time remains to be proven.

Novsight Warranty... Very Affordable Led Bulbs for Their Money. Strong and Sufficient White Light, Does Not Bother Others, Easy to Install. Highly Recommended!!
