Marsauto H11 9005 LED Bulbs Combo,LED Bulb Kit,12000LM 6000K Xenon White Bulb with Fan,Pack of 4

First I have to talk about customer service. Marsauto has exceeded my expectations. I purchased the low and high LEDs from this company and it took me less than 15 minutes to install all 4 of them. The only hiccup I had, was when I turned on my vehicle I received a “Check DRL System” that was pretty much popping every 3 seconds and would not go away. I contacted Marsauto customer support by email on a Sunday at 11pm and they replied to my request in less than 5 minutes. They were super nice and offered me a fix by giving me a 99% coupon for Amazon to purchase a Marsauto CANBUS decoder that is worth $29.99 and I only paid .30 cents. This decoder removes the flickering if you have any and also the annoying Daylight Running Light system error. I have never seen a customer service that good. All internet sellers should learn from these guys. I would definitely recommend Marsauto, not just because of the customer service, also because the products are high quality and the LED Lights I got from them were amazing. If I had 4 hands, I would give them 4 thumbs up. You guys rock!!!!!. I appreciate the excellent customer service provided. I will be more than happy to recommend your products to all my peers.

One of the stock low beam bulbs on my 2007 GMC Sierra burned out, and instead of just replacing the failed bulb with a new OEM style part, I decided to upgrade all of the headlight bulbs with this high/low beam combo kit. I'm glad I did, as I now have whiter, crisper light when I drive at night!Quality: these replacement bulb came secured in firm foam padding inside a sturdy cardboard box. The bulbs themselves appeared well built to me and felt substantial in my hands. All connectors, resistors, and 2-sided foam tape (for mounting the resistors) needed for installation were included and worked properly.Installation: twist out the old bulbs, twist in the new ones, plug the connectors into the vehicle wiring, and mount the inline resistors somewhere convenient. On my truck, the installation was a bit annoying thanks to the way GMC designed the headlight housings and how they mount to the truck, not because of any fault of the new bulbs.Light quality: these bulbs produce a sharp, cool white light - quite a change from the yellow-white of the original halogen bulbs. The LED light seems to reflect more efficiently from road signs - I'm able to see and read the signs from further away than with the old bulbs. Interestingly, although I feel that I can see further down the road with the new bulbs, there seems to be less glaring light hitting oncoming traffic. With my old halogen bulbs, oncoming traffic would often "bright" me even though I was using only my low beams. I have not had anyone "bright" me since I switched to these LED bulbs, so I consider this a safety bonus - I'm not blinding other drivers.Longevity: so far, so good. They've been in my truck for just over a month with no problems at all, but only time will tell if these new bulbs will live up to their longevity claims.

The first thing I'll say, is that these are fairly bright, and I have no data on longevity, so we'll see how that goes. They do seem fairly well built. Jury is still out on the fan though, and whether the fan will fail first or not.I installed these on a 2007 Tundra, and with the clearance for the bulb housings, it was a bit annoying to install these with the fan and heatsink case depth, but I was able to manage.The geometry isn't quite right though for the headlight housing, and these definitely shine vertically higher, into oncoming traffic more, and into the rearview mirrors of cars in front of me. The bulbs are fully seated and rotated in their sockets, so it seems the position of the LEDs isn't quite correct to match the original bulbs.The biggest gripe I have is that these are emitting radio interference. After I installed these, my radio signal would go in and out with static while trying to listen to a station when the lights are on. I've sorta gotten used to it, and it just isn't worth it for me to try to send these back, so I'll just deal with it when I'm driving at night. I did a test in a parking lot just to make sure, and the static would start when I turned the headlights on, and would completely go away when I turned the headlights off.Overall, I'd recommend you look somewhere else for LED replacements.

I used this kit to replace the HEADLIGHTS and HIGH BEAMS on my 2016 Chevy Colorado Crew Cab.SO MUCH BRIGHTER! Nice color.Installation is frustrating for ONLY to the nature of the vehicle. Just the same as changing the halogens.The entire assembly for each LED fits inside the sealed real light covers.I'm not sure if the aim of the light beam has changed or if it's just the brightness.The headlights seem to aim higher but nobody gives me a "flash".The passenger side footlight (same brand LED) really lights up the roadside.This kit was the only way I could afford to have all of the front lights changed to LED and MATCH in color and brightness.Looks like factory.

The light is very bright. The H11 low beam bulbs fit somewhat loosely in their headlight sockets. The 9005 HB3 high beam bulbs were very hard to install. Once installed, they were very wobbly in their sockets and didn't appear to seal properly. Suspect they would eventually vibrate loose from their sockets. The price was very reasonable. The poor fitment accurately reflects the price.

I installed these in my 2016 F150 and so far I really like them. Lights bulbs are hard to replace on an f150 and these aren’t any harder so I gave them 5 stars. Hopefully they will last but time will tell. Wish I had gotten the dog lamps too

I bought these about 4 months ago for my new 2019 F150. I do some driving at night and the halogen lights just were not enough. The LEDs are about 50% brighter and really make the lines on the road and the signs pop. Easy install from the wheel well. No flicker from either the regular headlight or the high beams. I'm very happy with these LEDs.

Got two sets of headlights was supposed to be fog lights and headlights had to reorder but they are very bright
