MARKCARS 8400LM Super Bright Cool White 6000K 60W H11(H8, H9) LED Car Headlight Bulbs All-in-One Conversion Kit Low Beam Head Light Bulbs Seoul Chips Car Driving Lamps Replacement 2 Year Warranty

Pros:1.Very bright.2.Way more bang for your buck than you get from an equivalent wattage high-end halogen bulb.3. Much easier to install and deal with than an H.I.D. retrofit installing projectors.4. Fewer parts than H.I.D. systems5. Cheaper than H.I.D. systems and cost per lumen actually makes these a better buy IMHO.6. Less light spread than H.I.D. conversions w/o projectors making them safer for oncoming drivers and you.Cons:1. Limited (read 1) option for color. 6000k is fine for snow, it sucks on dark rainy roads. I would have much preferred a 5000k option. At this juncture, if you live in someplace like Portland or Seattle where its dark and rainy all winter, halogens are better. H.I.D. systems with proper projectors are way better.2. Light spread is patchy and uneven with dark and light spots and doesn't give nearly as clear a view to the side as a good H.I.D. retrofit.3. There is still some light scatter when installing these into standard reflector assemblies so keeping your headlights aimed properly is a big issue and depending on your locale, could be the difference between tickets or no tickets.Conclusion: For my application, a 2000 Ford Focus "beater with a heater" in Alaska, these are simply awesome and I would buy them again.The car isn't worth doing a full retrofit on with projectors, and the stock halogens just couldn't compete against all the glare from other headlights coming at me on the road. These allow me to see even when pickup trucks with H.I.D. conversions are running their blinding low beams and fog lights at me. Rain only happens around here during the time of year when it's light outside for most of the day so my need for a 4500k bulb is limited. As they say, "your mileage may vary", so I would take into consideration your climate and your vehicles value and how long you intend to keep it before deciding between an L.E.D. conversion like these or a full H.I.D. retrofit. For maximum performance, the H.I.D. is the winner, but if youre on a budget, these are far more practical and far easier to deal with than an H.I.D. conversion.

Picked these up to replace standard headlights for 2015 Chevy Impala. The connectors fit, but either the metal wasn't machined correctly where it was supposed to twist in, or the plastic on my headlamp assembly wasn't machined correctly. However, I used my drill and shaved away a little of the plastic to get it to snap in and it was snug. The driver's side was very loose for some reason, but I don't feel as if it will fall out of place. The lights were bright even for the daytime, and they have a cooler bluish hue to them. As of now I will rate them 5 stars for the price. Autozone wanted close to $150 for a pair that were rated similar in terms of luminosity. A third of the price!? LED? Score! :D Total installation time for me was about 15 minutes by the way.

Got these for my fog light. Its definitely brighter than halogens and looks like it will last longer. Keeps the housing cooler.I'm use to using 2500k or 3000k hids and these 6000k looks just as good on the car.Simple plug and play. Had issues with getting the bulb socket to turn but eventually got it.

they looks good this was for my brothers dodge charger 2015 really easy to install if you know a lull about cars took me 5min to install good look :)

Had to do a little modification to my aftermarket headlights that are normally H11. The H1 worked fine after i purchaed some aftermarket connectors.

Love the headlights except one blew within the first week. Waiting to hear back from seller

I've had these on my 2015 GMC Sierra 1500 Denali for a few months now. Excellent quality and very bright. I have not had any issues out of them. Consistent brightness and no flickers

Put these on my husbands 2014 chevy. They were the finishing touch to making the truck look complete. They doubled his range of view at night.

I bought these bulbs for my wife's 2006 Mercedes SLK 280 which has H7 halogen bulbs in projector lenses and quite frankly this is a 150mph car with 50mph lights!! The other mither is the fact that the easiest way to replace the headlamp bulbs without ripping your hands to pieces,on this car, is a real chore, involving the removal of the front wheels and the plastic wheel arch liners. The bulbs arrived quickly in a very nice box and they look the business. First problem though, I found I needed a special bulb retaining clip to secure these bulbs in the holder. This isn't included or even mentioned in the advert. The one that holds the standard H7 bulb in place won't work. Then, after connecting the bulbs up to see how bright they were I found that one of the pair was faulty. It would come on for about two seconds and then go off for about four seconds and then back on again and off repeatedly. I swapped the connector around to make sure it wasn't a polarity problem but no change, it flashed as brightly and regularly as an aircraft landing light. The one that did work was very bright but I've got no idea how it performed on the car because I couldn't fit it. So, the bulbs have been returned and I've ordered an HID kit from a company with a phone number and a person I could speak to. My wife's car is now sitting on the drive, stripped down and waiting for DPD to deliver on their next day Saturday delivery promise, which was an additional £20, so I can get her car back on the road for Monday. Not a happy bunny!!

Good quality with amazing brightness far superior to original H7 it replaced. Only downside one motor vibrates for some reason. Only time will tell if it fails prematurely. Apart from that well pleased!

Value for money.My husband really delighted with this purchase.I will recommend to everybody who needs LED car headlights to buy these.

very good light bulbs, easy to install, well bright.I’m happy

Great light, however a pain to adjust.
