NOVSIGHTH4 LED Headlight Bulbs - 1:1 Mini Design 80W 18000LM 6500K H4/9003 Headlight Bulbs, Plug and Play, Replacement Halogen and Xenon H4 Bulbs, IP68 Waterproof, Pack of 2

I installed these in the dipped beam protector housing on my 2016 Isuzu D-Max Blade, the factory halogens are very poor and, as we get only five hours of daylight in mid winter, having good headlights is essential. They are a straight swap and took about five minutes per headlight to change.The lamps are bright, I would estimate at least 50% brighter than the halogens they replaced and on par with the factory LED headlights in my 2022 Suzuki S-Cross Ultra. The light is white, not blue like some of the cheaper ones, there is no flickering, and no interference with the DAB radio. Even if they do make a sound I certainly can’t hear it over the 2.5l twin turbo diesel! There are no errors but I don’t think my vehicle monitors bulbs.The beam pattern is perfect (I marked the wall with the halogens prior to fitting), and has a very sharp and clean cutoff. The attached image shows the D-Max dipped beam (left) and the Suzuki dipped beam (right). The Novsight bulbs are actually a bit brighter at the furthest point of the beam’s throw but slightly dimmer immediately in front of the vehicle. Build quality is excellent with an aluminium housing and small fan at the base, however there is no adjustment apart from the headlight unit itself (the same as with halogen bulbs). On my vehicle no adjustment was required anyway.If you’re fitting them to a D-Max make sure you replace the “clearance” (side) light with a W3W / 504 LED or it looks like an orange bulb! I also ordered a set of 9005 HB3 Novsight bulbs for the main beam but they haven’t arrived yet. I’m not going to attempt the fogs or DRL as they are a nightmare to get to on the D-Max, however the DRLs don’t come on if the side or headlights are on so not really a problem. I would certainly recommend these bulbs over the stock halogens on the D-Max. Yes, there are brighter and cheaper ones available but these are very high quality, comparable in size to a standard bulb and produce a perfect beam pattern, very important so as not to dazzle oncoming vehicles.

These bulbs were a lot easier to install than my last LED ones. With these you just pop in and twist (9005 type) and no need to adjust them.Good brightness and colour and there has been no flickering. Just keen to see how long they last.

My comments relate to installation in my 2006 Toyota MR2 - where the dipped beam (H7 unit) has a really compact, tight installation area, so my main pro's/con's may not apply to all.For comparison/reference, I've bought the last few versions of the Novsight H7 LED's:2017 "big red" - great light, really good beam pattern, but a MASSIVE heatsink that made them almost impossible to install in a tight space. I had to replace these dipped beam LED's due to an accident, but I still have the units (from 2017!) running as my fogs (HB4) + high beams (HN3), where the installation space is a lot more open.2019 "L-shape" - more compact heatsink, easier to install, but still difficult to keep fully secure... the LED units were also very small and the light generation point is not quite at the right place, so beam pattern was difficult to guarantee.2021 (these ones!) - the heatsink and fan is incredibly small and compact, so installation was very straight forward and they are now REALLY secure! The light generation point is larger and in a slightly different place, which seems to give an even cleaner beam pattern than my Halogens! As a bonus, the light is 6000K, so looks ice-white, without the blue tint of the 2019 version.I haven't voted on longevity as I've only had these a couple of days, but the previous Novsights have lasted 5+ years, so provided the compact heatsink hasn't shortened the lifespan, I'm expecting good things of these!

Straight forwards fitting, appears to be good beam pattern, brighter…Will there be heat problems? Durability problems?Ask me in six months!

I bought a second hand 2014 lecus CT200 and the stock lights were so bad, she wasn't feeling confident to drive at night.So bought thought and I have to say its day n night difference, literally.Installation was simple and performance is excellent, highly recommended.

I bought these after looking into several different LED bulbs and researching which would be best, and although it's a negative review and I would not recommend you buy them there are a few good points to the bulbs so I'll start with those.Positives: The bulbs are nicely packaged, appear to be solid and well built, are a comparable size to normal H7 bulbs, are very easy to fit, are a nice white light and give no errors on the dash,Negatives: Although the bulbs look bright in the headlight housing the light they throw onto the road is extremely poor, the light on the road is nowhere near as bright as the original halogens (Philips Racing Vision H7) that they were bought to replace, also in addition to the dimmer light on the road there were large dark spots in the beam pattern that were very distracting. I have since put the original halogens back in and there is absolutely no comparison - in my opinion you are far better off buying an upgraded set of halogen bulbs than LED replacements if you want to see the road better.

Very bright upgrade fitted to Hyundai i30, this did require a separate adapter kit for that particular car, but the bulbs themselves are great and the wiring extenders were useful too. Adapters were £4.50 or less from Amazon.

Bulbs them self are made amazing and shine bright but I had to put some effort to fit them into my BMW F20.
