Super bright, easy install and best of all no adjustments were needed to maintain the factory beam pattern and cutoff in projector housings. Also found that the bulb with heat sink and fan was still shallow enough to fit inside the headlamp housing without any modifications. Will be purchasing more in the future for other cars and fog lights.Can't describe how much better these are over the HID kits, easier install, lights are instant on, no extra boxes or wiring that needs to run through headlight housings, and the best part IMO is that the color temperature for both bulbs is identical. Will change the review if anything changes with the longevity but I don't see that being an issue, these are quality bulbs.Couldn't be happier with these, thanks!Tried a couple other LED headlights and these are by far the brightest. I was not thrilled that it had the extra black box along with it, but I wasn't able to find a set that was a direct replacement style for the standard headlight that were any brighter than they were.Just put these in and so far they are incredibly brighter. Will have to wait till night time to get a better idea of how bright they truly are. Follow the instructions and make sure you completely tight the LED bulbs. They do fit tight. Make sure you actually feel the bulb lock in place. If the bulb doesn’t work - flip the connection. This happened with mine and once flipped they came on.So far no fault lights or flicker noticed. No radio interference as well.I’ll update once I try them at night.Oh my gosh, I can't even begin to tell you how amazing these lights are!! I have such a difficult time seeing at night, these are so nice and bright that I have total confidence now! I loved them so much that I bought my mom a set too. Buy them!!I would have given this five stars except after install my daytime running lights stopped working. The seller had great customer service and worked with me as best they could to address the issue. I still have no DRLs but the regular headlights and high beams are far superior to the stock bulbs.They work as advertised. Fit my Titan pretty well. Just a fyi. On the high beam side it may be a little loose and wiggle. I fixed this using the old o-ring from the old bulbs slipped on far against the back of the socket. Solved the wiggle issue. So far I’ve been running them about a month. It was a amazing difference between these and stock lights. My windshield is also tinted with 50%. And I still have all the light I could ever need. Easy install as well.I would definitely recommend these compared to many of the others out there that have bad reviews and no customer support. Speaking of customer support I had to contact them in regards to finding the correct fog lamp size. They were quick to respond and very helpful. Don’t hesitate to get these. You won’t regret it.So, after about 30 minutes trying to install.... and looking at the stock bulbs trying to figure out why the new ones(low beams) wouldn't lock into place, I notice that the rubber gasket was inverted compared to the stock bulbs. I flipped the gasket around and wallllah! Be sure to flip them around if you're having troubles getting them to lock into place as well! Bulbs are nice and bright, love them so far!Installation was a breeze. It’s very bright. I can see much better at night. I recommended this brand of lights to all my co workers and friends. If you’re looking for LED headlights. Look no further.I brought these H11 for my Tarago low beam, since I were not sure the base height, the length from the lock ring to the base, due to the low beam housing, the dust cover does not given a lot of space. I emailed to their support, Mika from Fahren, he was kind enough to answer my questions, good support service, After I installed them on my Tarago, the light output was so bright, although they are only 30w on each bulb, one of the reason I brought them, they are a lot of brighter compared with the the sock bulbs, even better than those HIDs I have previously. The light pattern almost exactly same as the stock bulbs, this made me feel more safe to drive at night, particularly raining night.So……how did they did the test proven that this product is over 20000 lumens? Bright? Not as bright. I want my led headlights are bright as possible since the street lights in now a days are so damn dark.The low beam is is not bright as the Hi beam. I will try to figure it out if the problem from the bulbs or from the installationFrom Stock halogen to this Suddenly the vision of my car has improved drastically. It’s definitely worth your money. Only thing I didn’t like is the High Beam doesn’t go far as I was expecting, but the brightness is brilliant.Según es. Compatible para una silverado 2014. Hay s eve caramete que no es la altura
