Auxbeam H4 Fog Light Bulb, Fanless & Noiseless, 8000 Lumen 6500K Xenon White 9003 H4 Bulb Kit, Plug and Play, Canbus Ready NF-S1 Series (Pack of 2)

Got this kit for my motorcycles. Having a really bright headlight is excellent for safety so you can be seen by other traffic! I always ride with my high beams on during the day just for my safety. Great bang for the buck!

Install Details - 2103 Toyota Tundra Stock Headlights, low beams.These are great bulbs. Very bright and they seem to maintain the cutoff in the beam that the standard bulbs present. 5 Stars for the result.One of the two bulbs, however, broke within a week of installation. You can see in the picture the locking tab broke off. When I installed these, is took some pressure to get the locking tabs into the light assembly to twist and lock. Obviously, this was too much force for the plastic to take and two of the three tabs broke off.When I discovered the one broken, I pulled the other bulb and it was intact. The problem is that the blue seal ring is too firm and too thick. With the good bulb I simply reused the seal ring from the existing halogen bulb and it worked like a champ. Tight enough fit and will not move but a normal amount of force to lock into place. That bulb has continued to work.I contacted AuxBeam customer service and they were good with a replacement part. The plastic lock ring is a separate piece that slips over and screws into the actual bulb. It took about 3 weeks to receive the replacement as it had to ship from China. When I received the replacement I noticed the blue seal ring had been redesigned. It was not as deep and was softer than the original seal rings. I used the seal sent with the replacement lock piece and it went in without issue. I believe AuxBeam figured out the issue with the seals and modified so the tabs wouldn't break. If you order, check the fit and if it feels like you have to push hard to get it into the light and lock, stop, pull the seal off the original bulb, replace the blue seal, and go. Had this not happened, I'd rate these at 5 stars. AuxBeam Customer Service saved this rating from being 1 star.These bulbs have a large heat sink and you have to make sure there's enough room behind the original bulb to accommodate the increased depth. On my truck it is close but good. With the bulbs installed and lights assembly back in the truck, there's about 1/16" between the back of the heat sink and a piece of structure behind the headlight.

I bought these Auxbeam H11’s for my 2014 Grand Cherokee for it’s All-in-One sleek design without moving parts (fans), plug-and-play description and minimum input of 9VDC. The GC light housing has very poor access and you mostly have to work blind in the installation, but that’s a whole other story...The most important part of the installation, at least in my particular vehicle with projector housings, the LED’s need to be indexed at 3 and 9 o’clock for the absolute best beam pattern. Any other position of the LED’s and you will get an unfocused, scattered beam. And I believe this is true for all LED’s of this design, but each Auto manufacturer’s light housing may be different, so the exact index of the lights could be different from make to make.As important as this is, I am surprised that throughout all my weeks and weeks of researching LED headlight upgrades, that I have never read this note. It wasn’t until I read a review on Amazon, of a different brand of bulb by a user. This is why many of the 1-star reviews complain of a poorly focused beam and curse the product.This brings me to the “needs work” part of my review. In my particular housings, the 3 and 9 o’clock positions of the LED’s are not where the bulb locks in place. I had to remove the little Phillips-head screw from the bulb’s locking collar, drill another counter-sunk 45° off from the original, and reinstall. This way, the bulb locks in place with the LED’s in the correct position. Another issue, which is most likely isolated to my particular vehicle, is that when the LED’s are in their correct position, the oblong shape of the heat-sink prevents the dust-caps from being reinstalled. I needed to now remove the Allen screw from the heat-sink base and drill another hole 90° offset and reinstall.Now these modifications are not a big deal for me personally, but other less-experienced users may have a problem with this.After the modifications and correct install, the bulbs perform quite well. Probably just a little brighter than the stock halogens if at all, but give a wonderful pure white light. I have included photos of the bulb showing the Phillips and Allen screws needed to remove and rotate the collar and heat-sink base, and two photos of the lights installed and shining on my garage wall. 1st photo is about 10 feet away, the other is about 20 feet away looking from inside behind the steering wheel.The reason I wanted the 9 volt minimum input is so that the lights will still work with the 2014 GC’s DRL function which utilized the main headlight bulbs at a lower voltage to be slightly dimmer than for night-use. The LED’s DO dim, I thought that they wouldn’t, so this is actually a bonus. Edit:About 2 weeks using these lights, and so far no issues. I added a 4th photo of how the lights perform in pitch darkness. Here I was on a downward-sloping road approaching the intersection. I noticed that these lights really illuminate road signs from a great distance, 1/4 mile or more.As I mentioned, these lights might be a little brighter than the H11 halogens, but in comparison to a Lexus with factory HID or LED, these don’t compare. I’d like to get a set of 30 or 40 watt (each) bulbs. These are 25 Watts each.The locking collar on the bulbs is kind of flimsy, one of the tabs broke when installing. I have been in contact with the manufacturer, and they are sending me a “new item”. I asked for only new collars, but I’m not sure what they will be sending...I will report back when I get it...2nd Edit:I did receive a new set of bulbs from the manufacturer, I only wanted the collars. Out of all 6 bulbs that I had altogether, two remained in my headlight housings and are still in use 3 weeks later and perform very well. The other 4 bulbs had broken tabs on the locking collars and went back for return. I have to find a set that have a robust collar that won’t break.

I bought these to replace a set of other LED bulbs purchased in 2017 - those old bulbs used an external ballast and that ballast died.Replacement was easy (provided you have easy access to the bulb housing - varies per vehicle) - just twist the bulbs out, line up new bulbs (they have tabs so you can't put them in the wrong way) and twist until they lock into place. Make sure you follow up with headlight levelling to you don't end up blinding other drivers or have the beams all askew.I have projector beams on the car and these bulbs work extremely well (I have heard that reflector style lights can cause problems). For the price I can't complain and I hope these last at least as long or longer than the bulbs they replaced.

Perfect, as described with fast delivery!

Bought these to use as high beams in my Nissan Leaf to match the factory LED low beams rather than have the highs be yellow halogens. I rarely use the high beams but the odd time I have these seem to be pretty decent, about the same as the halogen H9 bulbs that were in there and the daylight white light matches close enough to be satisfactory, though being high beams I cannot comment on how these do for beam pattern. Install was quite easy, no extra driver/ballast module, and didn't have the problem with some aftermarket H11 bulbs where the gasket is too big/thick, these fit just right.

Me gustó mucho, buena calidad a un buen precio. Sin necesidad de hacer modificaciones al faro porque solo quitas el anterior y pones el nuevo sin ocupar herramienta

Super easy to install and make sure the lights are aimed well and the logo is facing the drivers side for both lights. If your beam pattern is distorted there is a good chance the lights are upside down. The low beams are powerful and the highs are ok. I use a set a Diode Dynamics SS3 SAE rated fog lights for additional visibility when on the highway. Quality seems pretty solid and lights don't overheat the rubber housing on a tacoma. I've gone off-roading and the lights stayed in place - snug fit. Time shall tell how long they last but truly for the $ value its a steal.
