Hoshi LED Headlight - Ultra Clear 6000k True White Light at 8,000Lm LEDs Lighting, Japanese Reliability/Low Heating. Internal Ballast, unibody Design CANBUS Ready

== UPDATE 6/27/19 ==After two years of service, the low beam chips on my left bulb started to flicker and then finally went out for good. The fan and high-beam continued to work. The manufacturer's web site is gone. I've gone back to halogens, which in the LEAF with its saggy 12V system voltage are like going back in time to even before halogens... at least they work and are completely silent.== ORIGINAL REVIEW ==I installed these into a 2016 Nissan LEAF SV, as it doesn't come with LED headlights like the higher SL trim. I didn't want leather, and had read the OEM LED headlights leave a bit to be desired in beam spread as well as the underperforming halogen high beams (H9 bulbs). The SV uses dual-filament H13 bulbs, so by upgrading to aftermarket LED, both the high and low beams can benefit.These LED upgrades arrived in a nice card stock box with each "bulb" safely protected in layered foam. A single sheet of paper was included with some precautions and installation tips. It could use a bit better translating to English, but I got the gist of it. One of the most important things is the machined adapter ring is removable and should be installed into the headlight housing first, without the bulb. The bulb then installs into this ring.On my LEAF, after connecting, I found I could slip the joined connectors in between the exterior dust housing and the reflector, saving room under the dust cap. In my application, I found the LED bulbs needed to be installed such that the LED chips were facing left and right, not up and down. Additionally, the LEDs needed to be oriented so the chip nearest the tip of the bulb was higher than the rear chip. Any other orientation resulted in incorrect beam patterns. Looking at the OEM installed orientation of the original H13 halogen elements confirmed this.Secondly, I found it very important to fine-tune the rotation of each bulb. There is just enough adjustment possible once mounted in its adapter to level the left and right beam patterns. In the US, the left beam pattern should be very slightly dipped from the right, but not too much. This is to avoid dazzling oncoming drivers. It was easy to adjust both to have a perfect beam pattern, just the same as, or possibly better than, the original halogen H13 bulbs.As these units have a built-in power supply, the OEM dust caps fit on without any drama. There seems to be enough air volume inside the dust enclosure to allow the heatsink fans to circulate are and stay cool. I measured 140F after 60 minutes of operation on a 50F evening. Removing the dust caps allowed the heatsinks to drop to 130F, so not a huge difference, and I wouldn't leave the dust caps off as you definitely don't want water or debris to get into the headlamps. Nissan seals theirs with an o-ring.In an electric car like the LEAF, you can hear noises you wouldn't otherwise notice in a vibrating gas car (thus the unusual headlight design to split air around the side mirrors to reduce wind noise). That includes the fans on these lights. It is a very quiet low frequency 300-400 Hz hum that phase in and out since the two lights don't have synced fans. Once underway or with the climate control on, the fan noise is completely masked.Pros:+ Affordable+ High quality construction+ Plug and Play+ Internal power supply / ballast+ Adjustable for beam pattern leveling+ Active cooling+ Perfectly mimics H13 halogen filament positions+ Very secure fit+ Pure, white, even lightCons:- Fans are audible- Sharp edges on heatsinks- Not US DOT approved

There were both Pros and Cons regarding this product, thus the mixed rating of 3. The product came quickly and was well packaged. LED brightness is just 'OK' - not much brighter than the original halogen bulbs, but much whiter and seems to spread farther L/R so they illuminate the ditches better (I live in the country and am always watchful for deer). They don't seem to throw a noticeably further distance, which I would expect of a brighter bulb. Install process was easy to understand (although on my car a big pain in the neck because there is no room to easily rach the bulb, but that is Honda's fault, not Hoshi's) but no directions, so it was good I had prior experience changing bulbs on this car.I ordered the H11 because the make/model finder on the web page said that was the correct one for my 2011 Honda Odyssey. Upon trying to install the LED, I found a couple of issues.First, the pins on the bulb cord that snap together with the wiring harness that used to go to the old bulb are spaced differently - by about 1/8". The connector seems the same, but on both bulbs and both wiring harness ends the spacing was off. I nearly returned them right there, but attempted to connect them anyway, and after quite a struggle I was able to get the connector to snap together well enough that the lights stayed on.The other issue that was almost a deal-breaker was the poor fit - which I have read about on other reviews. Both bulbs insert and twist to lock in place, but the rubber gasket on the bulb is too thin and the bulbs freely rotate and wobble loose. I fixed it on one by swapping in the gasket from the original bulb. This didn't work for the other LED (still too loose), so I cut a spacer from the original bulb gasket and double-stacked it with the LED supplied gasket - that made it tight enough to hold it's position.NOTE: when going back to Amazon to look up troubleshooting tips, my H11 order link now shows me a different Hoshi bulb that is NOT compatible with my vehicle - no search will being up the H11 LEDs any more.

I just finished installing these new replacement "bulbs" in my 2016 Jeep Wrangler Unlimited. I had been looking at complete replacement headlight assemblies for my Jeep, but the high cost and reliability concerns had me worried. I somehow stumbled upon these while searching through Amazon and they looked really promising. I did contact Hoshi before buying them and determined that yes indeed that they were the proper part that I needed and that they would fit into the stock headlamp assembly. This along with the warranty made them a no-brainer. The come is a sturdy package, and when you look and feel them you can tell that they are high-quality units. The only question that I forgot to ask is if these worked on both low and hi-beam. The answer is yes, they are a complete plug-and-play replacement for the stock bulbs.Installation was no harder than replacing the stock halogen bulb for the Jeep would be. You pop off the grill, remove the trim ring, and the headlight assembly just pops out. It took me about an hour to do the swap, but that was mostly due to me being slow and cautious. I could do it again in about 30 minutes.So far, I am extremely pleased with what I see. I'll post an update after a few nights driving with them.After dark update. The passenger side light looks good. Definitely brighter than the original lamp. The driver side is all screwed up. Everything snapped into place properly but the passenger side LED point straight up and down, the driver's side LEDs are at a 45degree angle and I get almost no light going onto the ground or in front of the car. Most of the light from it is going up and to the left. I'm also getting flicker.Next step will be to see if I can move things around with the left bulb. If I get that resolved I then see what Hoshi says about the flicker. Otherwise I'll have to go back to dim driving.
