Mdatt H4 9003 HB2 LED Headlight Bulbs - 12000LM 6000K -Hi/Lo Beam, Spotlight Fog Light Bulb Conversion Kits Upgraded Double JPS Chips Silent Fan IP67

I bought this product in Dec 18 here. Finally got around to installing them in early July 19. Installation on a 2006 Mercury Grand Marquis involves taking out the side marker first then the headlight assembly. Takes about 40 min per side, but not a hard chore.I checked each side before putting the lights back in. All looked good. I checked them again before shutting the car off. Again, everything was fine. However, when I went out later that night to check the lights, the passenger side light had only half the brightness of the drivers side. Half of the LED's had failed.I made an attempt to contact the mfg customer service, but my e-mail went unanswered.------------Update : After an initial e-mail asking me to pay for shipping for warranty items, they quickly reconsidered.The company is shipping out replacement headlights quickly with no fee. They are indeed standing behind their warranty and shipping out 2 replacements straight from Amazon.

Had to drop a star. These work perfect in my Subaru but my suburban also uses the same high beam and while it says they fit based on bulb size, the heat sink is a little more than a 1/4" too long to be able to reinstall the light assembly. The low beam mdatt I bought has the same issue at least with a suburban or similar GM vehicle. The heat sink hits against the front support structure not allowing reassembly. Usually for small clearances I would modify but this is the main front support structure of the vehicle and cutting or grinding it out would weaken it and shouldnt be needed in the first place.Find a way to cut the heat sink in half in size and I would happily order these again.

2009 Kawasaki Nomad 1700. It is true plug and play. No modifications were required. It fit perfectly. Wiring, connectors and balance appear to be high grade and well assembled. The manufacturer claims it is water-proof. I have no reason to doubt this claim.While I was doing the install I discovered a loose connection for the secondary running lamps. Repaired in short order.The LED is a quality product. It has a tiny built-in fan which operates silently and effectively. I do not have any sort of music system on the bike, other than my helmet's Bluetooth system. I can hear no sound interference.This LED is considerably brighter than the high end halogen it replaced. Low beam gives a wider and longer pattern which I like due to our wild life over-population. High beam is just that, VERY HIGH BEAM. Captain Kirk set phazors to kill. The light is a bright, pure white with no flickering. My multi-meter reads a much lower amperage draw.I compare them to a friend's HD Day-Maker at only 10% of the cost. Now to see if it will last.

Installed on 2005 RSX , H1 are not easy bulbs to find in led variety but i went with these after buying some defective out of the box winpowers. Compared these to a coworker h1 led from hikari and they are if not the same exact lumen output (left is a honda prelude with h1 hikari $40 version vs mine on right mdatt h1version)Overall im satisfied but i just wish they would of came with a longer wire and/or adapter to connect with the cars h1 harness like the other led kits come with. I had to really try to fiddle around with it because of the short length.

Just last week I got stopped by a State Tropper for having a bad headlight. The annoying thing was not that the light was burned out but unfortunately, that is was a faulty connection. The cop ended up letting me go with a warning but was still super annoying that I had to be making sure that the connection was good or I would end up getting a ticket.After looking at different options, I decided to purchase this one since it was a good price and I had always wanted to have LED lights on my car. The installation was simple (for a guy that is geeky, not very handy with cars). Got my light replaced and now they look great on my car. Very happy with the purchase

Just installed these in my 2003 Ford Excursion tonight so cannot yet comment about longevity.They seem to put out a good bit of light over stock aging bulbs. Color is very close to pure white with no blue. There are blue and yellow filters included if you want to be that kind of person.CAUTION: Make sure they are oriented correctly. The inner alignment plastic dowel slots can be rotated 180 degrees. Out of the box, mine were upside down causing the low beams to project like high beams - not good! I almost lost my cool until I figured out they can be rotated.The instructions are written in Chinglish, so your best bet is just to throw that paper right in the trash.

The media could not be loaded.  hese lights are FANTASTIC. They are "stupid bright" with a piercing 6000K brilliant white light and outstanding beam pattern. My 2016 Nissan Murano came from the factory with pathetically dim, halogen headlights These lights are very well made, crafted from machined aluminum and are truly a "plug & play" deal.. No adaptors, etc required. They work just like OEM headlights, are incredibly bright and have a perfect beam pattern in my 2016 Nissan Murano . I was suspicious about going with aftermarket LED's but after installing them in my truck, I would have NO PROBLEM recommending them to a friend.

Put these in an H4 7" round housing. The beam pattern is better than the h4 halogen. Low stays low with no weak spots. High beam adds height and distance to lows that stay on. So far, no complaints from oncoming drivers. Just know that on Wrangler JKs you need to buy a PWM harness for anti-flicker, and 9mm ferrite chokes to stop the radio interference. Don't go cheap on the PWM. The Rigid ones worked for me. Put a choke before and after the LED driver box.
