Well, it's time to write a review about these bulbs. Having bought over 10 pairs of Novsight bulbs for my car (Toyota Corolla E12, it's been almost 1.5 years now - there is a similar review for the LED H7 bulbs) and for my father's car (Toyota Auris 2009 - LED T10, C5W/C10W, H11 & HB3), I have a complete picture of the company and their performance.

Let's clarify two things:
1. These bulbs are the best value for money, and for me, there is no competition. Especially when compared to well-known brands (Philips, Narva, etc.) which cost twice or three times as much. AND they come with a 2-year warranty. And I'm talking about a warranty that even covers the T10 bulb, which costs only 70 cents. Incredible...

2. I recommend installing them in headlights with projectors, like the Auris, because in my car, the Corolla, which has reflector headlights, the light is scattered everywhere, which can be more pleasant for driving because you can see everywhere clearly, but it can be a bit annoying for others (I adjusted mine to be low and I'm still a bit annoying, while others are very annoying because they aim high).

Now, regarding the matter at hand: I installed these bulbs for fog lights in the Auris, and for that, I am attaching photos comparing the fog lights before (yellow) and after I changed them to LED, just like I did with the high beam using a different type of Novsight H11 bulb (there is a review for that as well) to test them all. These bulbs are truly amazing in terms of quality, brightness, color, and sturdy construction. They are the best value for money. The installation was a bit tricky in terms of the bulb, but everyone should study their own car separately because not all headlights have the same space for you to put your hand and work. Personally, I struggled a lot with the high beam in the Auris (Novsight HB3, there is a review for that as well) because the fan of the bulb is big and couldn't fit inside. In the end, I unscrewed two screws from the headlight, pulled it out a bit, loosened the radiator, and it fit. But the high beam and fog lights, where I used H11, were very easy. I personally changed ALL the lights in my father's car and even changed all the interior lights in both cars with bulbs for the dome lights from the same brand (Novsight Nighteye). I highly recommend it. Tremendous results in both cars. No reason to worry. Only comparing the price with equivalent branded LED bulbs will help you understand why you should get these. The cost of changing all the bulbs in a Toyota Auris in all lighting areas (low beam, high beam, fog lights, T10 bulbs in the front and license plate, driver and passenger dome lights, and trunk light) cost a total of 96€ with Novsight. The equivalent installation with Philips bulbs, for example, would cost 226€. That's it from me... I hope I helped.
