Sent back not bright enough

The product was good. I bought it for $58. But one dies after 5 days. They should improve the quality. Otherwise it has very good brightness of it's price.Overall, not happy with the product.

The locking ring to secure the bulb to housing does not fit over the flicker box or the fan. It is useless as it cannot be installed

These LED replacement bulbs provide an amazing colour and brightness, significantly surpassing other higher priced brands. And while I honestly can't say how the longevity will be, at this point, all of the aspects of the material and construction, shows a high likelihood of providing reliable lighting for 50,000hrs+-. But again, time will tell.First off, to say that these provide %800 of the normal brightness levels would seem to be justified, when compared to OEM halogen bulbs. And while I have tested approx 100 different bulbs, I can say in good conscience that these are a very good bang for the buck. And while I can take pictures of the bulbs on a dark road, it will not give a fair assessment of the bulb. Bright white light is hard to determine in photos, without perspective of the area. But the main value is with the material and construction quality. And with alit of LED bulbs to choose from now, having bright lights is easier than ever. But having them work well, and for longer, is the biggest part.So these provide a reliable, plug and play design. They have not disrupted my factory DRL, light modules, or given any adverse humming or buzzing feedback to my vehicle. And while installing takes a little effort in my truck, the bulb body dye, allows a very secure lock, that position exactly where meant to be for the perfect beam angle. Taking away the annoying need to have other drivers flash me, because my headlights are poorly aligned! Please ensure your headlights are properly adjusted. Especially with new high powered LEDs. Rarely, you can just put a set in, and not have to adjust your beam height, unless you're replacing from LED and previous adjusted. But also, the way the bulb is positioned in your bezel, will make a difference too. You may have to turn the lock tab, if required and available. These are ready to go, with perfect alignment.Now the bulbs have excellent, well sealed seams. As you can see in the pictures, the connector, chip, and body of the bulb, is very tight. And with the higher quality metals used in the construction, it is less likely to have corrosion being a problem over the life of the bulb. Although most vehicles have the bulb areas sealed within the light housing, to aid this as well.As tested, I allowed a bulb to hang outside while I completely soaked it with a hose. I then turned the light on and drive down our bumpy back road, allowing it to bounce and bang around. I avsude the bulb, way beyond the normal expected conditions. And after an hour of dust, dirt, water, and banging around, I removed it, cleaned it up and dried it thoroughly, and installed it properly. And more than 2 weeks later, the bulb has the same brightness as the unabused bulb. And is continuing to work flawlessly. Without humming or interference of any kind.So again, for the overall quality, and functionality of these bulbs, I feel them to be an exceptional bang for the buck.

Completely satisfied. Easy to install and super bright no flicking and best for projector headlights

These LED bulbs were the brightest in the market, until one of them stopped working in just the first week. Novsight has lost its quality indeed. The first set I got was a $40 range one and lasted over 3 yrs. I thought this premium set would get me for longer. I guess I was wrong. Total disappointment.

It's very Bright and looks pretty it just getting too hot right away maybe because of the wattage but looks good

I bought the same bulb in 2021 and was absolutely amazing. However the bulb has been changed in its design and is not as good as the previous one. Beam patern is vague. And the lumens seem to be slightly dulled.

I have tried all sorts of led bulbs for my cars, these are by far the best, so far, super bright, only problem I can see is they don't light the road up far enough ahead, amazing headlight leds. Would recommend, also fitted within 5 mins,

I tested a few brands out before making a decision and these bulbs were some of the brightest around - way too bright for road use! The unfortunate bits about these bulbs are that they get exceptionally hot (will burn close objects), and the H7 mounting plate is much thicker than standard bulbs which meant they couldn't clip in properly.

I fitted these because my 55W halogen projector headlamps were like candles and I couldn't see the edges of the road when one of those excessively bright 2020s cars was coming in the opposite direction. Projector headlights are about half as bright as ordinary reflector headlamps with the same bulbs.These things work brilliantly. Now I can see perfectly and I get a good controlled beam pattern in the projector lights. Comparing with other vehicles on the motorway my beam with rubbish projector headlamps is just as bright as the latest 2022 LED powered Audis and a few times brighter than any other modern car.I am uneasy competing in the headlamp wars. I feel these are way too bright for road use. I've not been flashed yet, but it is becoming the norm to have to squint at excessively bright headlamps. For my car I would have been just fine choosing the 25W option for half the price. I might still do that and put these monsters in the high beam instead.I chose these particular ones for the thermal management. It's heat that that dictates the life of an LED bulb. The big cooling fan behind the bulb and the separate driver box should help a lot. Haven't had them for long.
