9004/HB1 LED Headlight Kits-Flip 4 Sides COB Chips- Car Headlight Bulb 9004 240W 24000lm HB1 24000LM Super Bright 6000K-Dual Hi/Lo Beam Replacement Bulbs Pack of 2

- The Positive/Negative polarity was switched on all 4 of my bulbs. When installed backwards, the cables don't lock together.* The fan/base of the LED protrudes further than the stock lights, and caused problems mounting them flush. This is common for LED bulbs; not just these.* There is no apparent difference between the 9005 and 9006. Stock lights are keyed differently at the plugs; these are not. This could be a feature making them hot-swappable, but its a bit more confusing when installing.* The highbeam and lowbeam are the same power, the difference is the angle inside the headlight housing.* The box does not identify the difference between the 9005 and 9006. The only difference is the red band or black band close to the bulb.Now that all my gripes have been noted, its a good product at a great price. The minor frustrations during the install will be avoided by anyone reading this review. The lights provide good vision at night, and are bright. I don't see any reason that they won't be the last headlights I ever install in my truck.

Ordered these for my dad, I installed them. They seem decent enough but I'm not an led fan. I like hids personally and have never drove with LEDs. Dad says they are amazing. As for me ~shrugs~ I don't know. I'll stick with my 55w hid kits.. not knocking this product, I just don't trust LEDs. Dad sure seems to though.My personal thoughts against dad's review is simple, these LEDs don't replicate a Halloween at all which is a very bad thing, they have no hot spot like my Hikira LEDs do... They are cheaper than Hikira but only slightly better than a 100w halogen and slightly under what a 35w hid kit is... But both halogen and hid outperform these in my opinion... 3 months later, I was right... These are horrible quality, both sets already burnt up.Emailed both Amazon and seller, let's see who responds first!!!-will update everyone on isuue.... - guys for now go auxbeam or hikira.

I bought my brother is a kit with all four bulbs for his 2014 Chevrolet 2500 HD for Christmas I was kind of wondering about how they would work because the price was so cheap at $55 for four bulbs. When they arrived I opened them up and took a look at them scanned everything was totally fine with them and we put them in his truck on Christmas Eve and he couldn't be happier. They work great and are bright as all hell. I purchased another set in my own truck that cost twice as much for one set of bulbs and these ones are brighter. The only one thing I wasn't that happy about was the boxes did not have different part numbers on them so he thought they were all for the same at first but I was able to tell the difference by the way they connect to the housing they only fit in one way but that's not a big enough deal to even drop a half a star in my book please get at 5 all day and I would buy them over and over again✌✌✌

Was super excited to get these! After unboxing I could tell they were quite a bit bigger than originals. Not clear on which is high and low beam but when removing the old ones you can compare and find out what goes where. Top went in fairly easy but could tell the tabs came loose because it's not a good match. Then went to the bottom light and tried to twist it in and it would not go. I continued to try and the plastic tabs stripped out and the mounting screw fell out.... Of course I couldn't find it... Had to steal one of an old lighter and luckily it worked. However the still wouldnt go in and I was afraid it would strip again. I had to remove both of the headlamps entirely to install them with out breaking them. So quite of bit of work removing air box,grill,fender flares,and more plastic but finally got the job done. Then they didn't work... Had to tear it apart again and mess with clips to see if they were backwards. That wasn't the problem.... The problem is now my lights don't automatically come on like they did previously. I have to do it manually now and I have no clue why... Also my battery is dead now and I dont know if its because of the lights or because I messed with them so much.. By the way this was on a 2008 Chevy Silverado lt 1500. I will say they work and seem bright. However they seem cheaply made and break easily and do not fit correctly. They are not easy to install at all if you want them to fit semi correctly. If anyone knows why my auto lights don't work please let me know.

Purchased a set 10-18-19, and installed without issue in my 2011 Chevy Silverado. I have been very pleased with the light output from these bulbs. About a week ago one (1) of the low beam bulbs has failed. These come with a 2 year warranty and I would appreciate some assistance from ZhanGe in replacing the bulb. Tried to go to web site but without success. Please help.

I got these for Christmas 2018 and they worked great up until last month, not sure what happened; however, anything man-made can go out just like a TV, mobile phone, microwave, etc... I reached out to the seller and first off their customer service is wonderful. They also respond back to you very fast & offered a solution that worked for both the customer and seller.Buying these for my other vehicle.

I got two sets of led headlight replacements, these and a set fulfilled by amazon. The set I got from amazon consumed about 25-30 watts. this set although they claim 140 watts, which I assume is for both of them, consumed almost twice as much as the amazon set at about 50-60 watts a piece. not quite 140 as they claim but more than enough to replace a 55w incandescent or one of the 35 watt hid kits that are common on amazon and ebay. cant say much for their lifespan since I just got them, but they seemed good quality and the mounting was great and could be adjusted. Fit my Audi Q7 very well.

I had to remove them and install regular halogen lights. The fan was messing up my backup camera (picture was distorted). Also the small screw that holds the light to the housing was touching the light housing and grounding it out messing up my blinkers on my toes Mirrors.
