I'd purchased these a while ago but didn't install them until today.Something about all the videos that indicated replacing the low beam headlights was going to be a pain and largely completed by feel. Other videos had folks replacing the entire housing, which would simplify the actual bulb replacement, but could require re-aiming of the headlights after install.We got nice enough weather her in the NE today and I finally decided to give it a try to replace the headlamps through the wheel wells. Boy, was I right. Replacement of the low beam headlamps (installed above the high beams) was a true PIA. Getting the waterproof boot off was easy enough, but trying to disconnect the bulb one-handed proved almost impossible. I was finally able to do it and found that reconnecting the replacement was also a one-handed task, guided largely by feel.All told, it took about 2 hours to complete both sides.I must say, though, the brightness over the old yellow halogens is quite noticeably and appealing - even in late afternoon sunlight.It's going to be nice to see further when driving at night!Highly recommended - especially for folks with skinny arms. :-DUpdate 5/2/2022 for my 2020 F-150. My 2017 F-150 failed and it forced an upgrade to a new-to-me 2020 F-150. Unfortunately, the 2020 came with the dim halogen bulbs.I installed these yesterday along with LED fog lamps. The installation process is a bit of a challenge, especially for the low beam bulb replacement, but my experience with my 2017 let me know what I was up against.It's nice to see the road again!

First off, thanks to the people here and on the gm-trucks forum for the product recommendation. For some reason, the Amazon parts compatibility engine doesn't think that the H11/H8 Low Beam 9005/HB3 High Beam combo fits in the 2020 Silverado Custom Trail Boss, but it does.I didn't find time to install these until more than two months after I ordered them, so I'm glad that they did fit, since I was past the return date. I was expecting a painful installation, but it was nothing of the sort. I am an experienced amateur mechanic, so maybe that made it easier. Plus, I have long skinny arms, so I'm sure that helped also. I read on the gm-truck forum that some people removed the T15 torx bits from the inner fender wells and went that way to get to the bulbs, so I was prepared for that, but I never had to do that.I started on the passenger side, since there seemed to be more room over there. I removed both rubber dust caps, but just pulling on them and rocking them until they came loose. I worked on the upper (low-beam) bulb first. I just reached down, twisted the bulb counter clockwise until it released from the light assembly, and the pulled the bulb out. I then reached down and pushed on the retention clip to remove the bulb from the electrical socket. Since the LED H11 bulb has retention clips on both sides of the connector, it could clip in either way. At this point, I got out my multimeter to determine the polarity of the connector. I turned on the headlights and put my meter on the leads until I saw which one was positive (red probe on the positive side and a positive voltage showing on the meter). I used a red sharpie to mark the red side, then turned off the headlights. Looking at the truck's connector from the front, with the retention clip up top, the right side was positive. This was the same for the low beam on both sides of my truck.After determining the polarity, I connected the + side of the LED connector to the side I marked red, then I gently maneuvered the LED into the light housing's bulb hole. Starting at the angle that I removed the old bulb, I reinstalled the new bulb, wiggling it until it was flush against the housing. I then rotated the LED bulb assembly down until it was vertical and against the stops in the housing. Before going any further, I turned on the headlights to make sure that the new bulb came on, and it did. Wow, these are bright!After verifying that it worked, I took all of the cables, and arranged them inside of the bulb assembly, so that they fit under the dust cap and nothing was blocking the fan. I've attached a picture showing everything in the assembly, but before I finished adjusting how everything laid in there. After getting everything inside and situated, I reinstalled the dust cap. This was done by just pushing on one side and then working my way around, applying pressure around the circle until it all was flush with the plastic. Not difficult at all.I again turned on the headlights to verify that the low beam still worked. I moved down to the lower bulb, which is the high beam. I did the same thing as above, twisting out the bulb from the housing, then disconnecting the electrical connection. Luckily, the LED 9005 high beam bulb only has a retention clip on one side, so I didn't bother checking the polarity. I clipped the electrical connection together, then put the new bulb into the housing, rotating it until it locked down. Again, I tested the lights, this time activating the high beams to verify that it worked, which it did. I then arranged the wires and reinstalled the dust cap.Onto the driver's side. This was more difficult as the wiper fluid bottle of over there, limiting hand room. But, I said a quick prayer, and worked by feel, removing the dust caps, then the low beam bulb. (Make sure it isn't hot from being on earlier, or you could get burnt.) I tested for polarity and it was the same as the other side. Hooked up the electrical connector, Installed the LED bulb into the housing and locked it into place. Tested the low beams and it came on. Arranged the wires inside of the housing and reinstalled the dust cap.Onto the lower, high beam bulb on the driver's side. This one was a little tight for access, but I was able to reach down and get the bulb right out with no problem. Do as the other one, hook up the electrical connection and insert the LED bulb into the housing, rotating it into place. Test the high beams and it too worked. Arrange the wires in the housing and reinstall the dust cap.All done and it probably took about 30 minutes, with me taking my time. If I knew it would have been so easy, I would have installed them sooner.I also took this opportunity to adjust my low beam headlight height. For some reason, I felt that my low beam pattern was not projected high enough. Using a long, #2 phillips screwdriver in the adjusters, I rotated to the left (like loosening a screw) one turn and it raised up my light pattern slightly. I was aimed against my garage door and saw the pattern move. I was surprised that the owner's manual didn't have instructions to adjust them, saying that they were preset at the factory....Anyways, these lights were pretty easy to install and are incredibly bright. I don't see any flicker or any other problems.I wish this technology existed seven years ago when I installed HID projectors in my motorcycle headlight housing. I would have just put bulbs like this in instead, as it would have been much easier, but I do like the sharp cutoff on my HID projectors. (I don't like having a mechanical shutter for the HID high/low beam on them though.)

Very happy on this purchase. Some say LED is as bright as the standard bulbs but I dont agree they are blindingly bright. Not sue to the Color change even thought its big improvement too. I went from a Hint of amber to Bright white.These bulbs light up the whole road and its much needed. Price is high compared to your standard bulbs but longevity should mach or even last longer hopefully. But if not then perhaps a lower star rateing is due but right now only time will tell. My OEM bulbs were still running great at 11 years old but I wanted brighter and whiter. These LED bulbs fit thatNow installation. Its easy as just pulling old bulb out and putting this one in with an extra step of ziptying the extra bit. Pretty easy install......Unless you have a 2010 Honda civic. lolIf you have a Honda civic you need to remove the reservoir container on the driver side. Not hard it pops in and out. The hardest part is the driver side. No room to put hand down through engine bey so you need to turn you wheel inward and pop the wheel well liner in order to replace this bulb or any brand headlight bulb and its a pretty tight spot. But with a little time you can do it. Its worth it.Side Note: I did not have to readjust by headlight levels as this was an easy plug and play and remains at the same heightRight now im extremely happy with this purchase. No we see how long they last.Want a brighter whiter light that should last 30k+ hours then get this one. Way cheaper than $200 like most bigger brands

Did not fit in mercedes w211 e class and its not error free, shows up error code and light blinks when installed, have to return sadly, it was bright though

Simple upgrade ... 5 min per side

Pretty nice lights I installed the fog lights and the reverse lights on my 2015 Acura ILX . A lot better than original lights they’re very bright , I plan on changing my DRL and my interior lights.

Way brighter than the standard halogen reverse lights in my 2017 Honda Civic LX. Very premium appearance. Thank you.

LED lights to fit a 2015 Subaru WRX.Installation was easy, and only required the removal of a few push-pin fasteners to access the back light. Overall, the install took about 20 minutes for both lights, and the difference is huge!It's like having headlights for taillights, and this is perfect for backing up at night, as I can see everything behind me. A huge improvement on the stock bulbs that come in most cars. This is a must upgrade in my opinion.
